Published: December 2019

Os arenitos associados a modelos episódicos de inundação, como os Inunditos provenientes de fluxos hiperpicnais em corpos de água rasa, podem ser reservatórios de hidrocarbonetos. No entanto, há poucos estudos para entender a arquitetura e heterogeneidade desses modelos, o que resulta em dificuldades para exploração e explotação desses reservatórios. O presente trabalho visa à análise de pacotes triássicos da Bacia do Paraná pertencentes à Formação Santa Maria, que ocorrem como fragmentos isolados sobre o Escudo Sul-Rio-Grandense na região do Gráben Arroio Moirão (Rio Grande do Sul). Para tanto, fez-se um estudo comparativo de modelos de inundação e como metodologia de obtenção de dados utilizou-se mapeamento sistemático, análise de heterogeneidade de fácies e estratigrafia de sequências, que incluem levantamento de perfis colunares, identificação de associações e sucessões de fácies e superfícies-chave. Secundariamente, algumas análises petrográficas foram realizadas. Foi possível delimitar os principais depósitos de arenitos, dos quais predominam geometria tabular, grãos mal selecionados e alguma matriz argilosa. Distinguiram-se cinco ciclos deposicionais granodecrescentes ascendentes, limitados na base e no topo por superfícies erosivas, que marcam heterogeneidades recorrentes. As fácies-reservatório são subarcósios, de matriz argilosa com agregados de caulinita, porosidade intergranular e shrinkage. Identificaram-se potenciais fácies-reservatório constituídas de arenitos grossos a conglomeráticos, com estratificações cruzada tangencial e plano-paralela. A integração dos dados resultou na elaboração de um modelo de variação lateral e vertical de fácies de hiperpicnitos lacustres, como um potencial modelo análogo de reservatório do tipo compartimentado. Esses resultados possibilitam prospectar outros depósitos arenosos dessa unidade estratigráfica da Bacia do Paraná, para fins de dimensionar regionalmente o análogo de reservatório.
Geologia, controle estrutural e mineralogia do escarnito mineralizado em ouro e tungstênio da Mina Bonfim-II, Província Borborema, Rio Grande do Norte, Brasil
Authors: Pereira Eduardo Henrique Rodrigues , Botelho Nilson Francisquini , Oliveira Claudinei Gouveia de , Santos Eduardo Valentin dos 
Published: December 2019

A Mina Bonfim é caracterizada por camadas de mármores em contato com flogopita xistos subjacentes, ao longo do qual se desenvolveu o escarnito rico em tungstênio e ouro, disposto seguindo a orientação N10ºE/30ºSE, cisalhado e estruturado sob a forma de boudins, em baixo ângulo de caimento (12º) ao longo da direção N10ºE. A scheelita encontra-se nos boudins, associando-se à molibdenita, ambas sendo formadas sob condições sin-tectônicas dúcteis, consistindo na primeira fase de mineralização. O ouro encontra-se em fraturas de cisalhamento tardias, com orientação N70oW/75ºSW, que seccionam e deslocam o escarnito scheelitífero. As fraturas são preenchidas por prehnita (ganga), ouro e minerais de bismuto, indicando que a precipitação do ouro ocorreu na fácies prehnita-pumpelliyta, sob regime dúctil-rúptil, que corresponde à segunda fase de mineralização. O ouro é rico em prata com até 16,09%Ag, e suas formas de ocorrência são: livre na ganga, em fraturas ou em contato com bismuto, bismutinita e joseíta, constituindo a paragênese aurífera. Grãos de ouro exibem bismuto na composição, podendo chegar a 0,44%Bi. O minério está hospedado em escarnito reduzido, gerado em estágios progressivo e retrogressivo, produto do metassomatismo em mármores alterados por fluidos carreados ao longo de estruturas.
Sismoestratigrafia da seção Campaniana-Maastrichtiana da Formação Calumbi no campo de Carapitanga (Bacia Sergipe-Alagoas)

A Formação Calumbi tem parte de suas reservas de petróleo e gás preservada no campo de Carapitanga em rochas de idade Campaniana-Mastrichiana da Bacia de Sergipe-Alagoas, produtor de acumulação marginal da área norte da bacia. Apesar de seu importante papel na produção regional de hidrocarbonetos, as sequências deposicionais do campo têm sido pouco discutidas na academia. Com o objetivo de contribuir para os modelos de sequências deposicionais do Cretáceo Superior, analisou-se a sísmica disponível do campo sob a ótica dos conceitos de Estratigrafia de Sequências. Os resultados obtidos sugerem três sequências deposicionais de curta duração (3 – 10 Ma), com desequilíbrio entre subidas e quedas entre si, o que contrasta com as premissas dos modelos de sequências. Estas se distribuem em três cânions com até 10 km de largura, 282, 202 e 102 m de espessura, respectivamente, situadas na transição Pré-Campaniano-Campaniano, Campaniano e Mastrichiano. A primeira sequência é formada por quatro tratos de sistema, com pequeno desequilíbrio entre dois eventos transgressivos de menor duração em relação a dois eventos regressivos, que registram a sedimentação dos tratos de mar baixo e transgressivo, correspondendo aos melhores candidatos a rochas-reservatório do campo. A segunda sequência, mais jovem, preserva três eventos de regressão e um de transgressão; e a terceira sequência tem comportamento similar, porémcom maior duração de queda. O padrão de variação do nível de base é pouco harmônico e contrasta com a curva senoide adotada para predição de geometrias deposicionais em bacias de margens passivas e com os modelos interpretados ao norte da bacia, no qual foram identificadas quatro sequências. Os cinco picos de queda registrados parecem estar relacionados às flutuações
Geological mapping of intrusive rocks: a case study in the Garzón region, the Eastern Cordillera of the Colombian Andes
Authors: García-Chinchilla Daniel Alejandro , Vlach Silvio Roberto Farias 
Published: December 2019

Jurassic granites (sensu lato) and related rocks are the most abundant rocks cropping out in the Eastern Cordillera of Colombia in the northern Andes. We present an attempt to map and characterize in detail the petrographic diversity of the Jurassic granites and related subvolcanic rocks emplaced in the Garzón region, southernmost the Eastern Cordillera. We also provide new geological maps for the Algeciras and Altamira Plutonic Massifs based on descriptive concepts of the petrographic facies and facies associations and detailed petrographic and mineralogical characterizations of the observed granite types. Eight plutonic and three subvolcanic petrographic facies or facies associations were mapped in the Algeciras Plutonic Massif, and another five in the Altamira Plutonic Massif. Hornblende biotite granites (syeno- and monzogranites) are the main plutonic types constituting the first massif, while leucogranites prevail in the second massif; a zoned facies distribution was mapped in the Algeciras Plutonic Massif. Felsic porphyries (dacite and rhyolite) crop out as minor irregular intrusive bodies or dikes and mafic-intermediate syn-plutonic dikes (mostly microdiorites) cross cut the main plutonic rocks in both massifs. Geological and petrographic characteristics (e.g. micrographic textures) suggest relatively shallow emplacement levels for the plutonic rocks as well as slightly high uplift and erosion rates at the north of the studied area. Local penetrative solid-state planar structures and dike orientations conform with dextral strike-slip movements along the SSW-NNE trending Algeciras Fault System in a transpressional regime associated with a major compressive and oblique convergence in Jurassic ages.
Da inconstância da fortuna. A teoria e a metodologia do restauro em contexto Europeu
Authors: Mendonça Lisandra Franco de 
Published: December 2019

O restauro do patrimônio edificado na Europa ocidental evoluiu de um entendimento inicial agarrado à marca da reconstrução estilística e da conservação a qualquer custo para políticas de tutela e estratégias de gestão patrimonial que implicam um julgamento equilibrado de diversos valores e recursos. Este texto começa por explorar alguns aspetos históricos e conceptuais do restauro e o aparecimento e o desenvolvimento da tutela do patrimônio tal como é entendida hoje na Europa, percorrendo vários contributos teóricos, de forma a delinear variações significativas do suporte teórico e das metodologias de intervenção correlacionadas. Não reentra nos objetivos desta sintética “aproximação ao restauro” o aprofundamento exaustivo da sua gênese e das práticas patrimoniais em contexto europeu – a bibliografia nesta matéria é extensa e atual –, mas apenas evoca alguns momentos determinantes na evolução da sua organização teórica e prática. O formato do texto impõe uma escolha limitada de atores e estudos referenciados, forçosamente arbitrária.

Observations on the ex situ management of the Sumatran Rhinoceros Dicerorhinus sumatrensis (Mammalia: Perissodactyla: Rhinocerotidae): present status and desiderata for conservation
Authors: Nardelli Francesco 
Published: December 2019

The Sumatran Rhinoceros is approaching extinction. A few dozen animals remain, dispersed in dwindling Indonesian rainforest with only a few years of likely survival time. Eight rhinos belonging to two subspecies are in controlled breeding centres. The Sumatran Rhinoceros differs markedly from the other four species of Rhinocerotidae and requires management according to specific protocols. Several Sumatran Rhinoceros have died in zoos, owing to lack of knowledge concerning their particular dietary requirements and their high sensitivity to anthropogenic activities. Recently more positive results, including successful births, have been achieved with the aid of scientific research, which continues to examine factors required for successful conservation and accommodation efforts.

Published: December 2019

A concise interpretation of people’s perception and attitude towards wildlife helps in formulating better long-term conservation policies. In an attempt to understand people’s perception, we considered one of the threatened and least known ecosystems of northeastern India, the Barail range, mainly focusing on the Barail Wildlife Sanctuary, the only protected area of this range, and falls in the Indo-Burma biodiversity hotspot area. The sanctuary is known for a high diversity of mammals, mainly primates (with seven reported species), and bears (with three of the eight globally known species—a diversity not met elsewhere in the globe). To protect its pristine wildlife wealth, it is essential that the perception of the local settlers is elucidated, and this prompted us to take up the present study. In this study, we used open- and close-ended questionnaire, which was then coded (yes/positive=1 and no/negative=0). Each response was thoroughly examined using logistic regression and variables like socio-economic factors, knowledge of the sanctuary, wildlife and forest management were found to generate positive perception towards the sanctuary and its wildlife, and vice-versa. Further, alternative means is suggested in terms of tourism, and the attitudes towards instigation of tourism were mostly favoured by the locals. Besides promoting tourism, providing alternative livelihood and vocational trainings for the locals and, timely compensation for the losses caused by the animals should be long-term strategies for the conservation of the mammals of the sanctuary. It has been increasingly recognized that involvement of locals is a prima facie requirement in the conservation of wildlife, and as such their perception is of great significance. While the study was conducted at the Barail Wildlife Sanctuary, the results may translate in other protected areas, and may be referred to as a model strategy for other protected areas having similar scenario.

AbstractThe Innsbruck Atmospheric Observatory (IAO) aims to investigate atmospheric chemistry, micrometeorology, and mountain meteorology in a synergistic fashion within an urban setting. A new measurement supersite has been established in order to study processes affecting the exchange of momentum, energy, trace gases, and aerosols in an Alpine urban environment. Various long-term continuous measurements are augmented by frequent focused research campaigns with state-of-the-art instrumentation, linking different classes of data and addressing significant gaps in scientific data availability for urban environments. Current activities seek to address research objectives related to the urban heat island, trace gas emissions, the influence of foehn on air quality, and the atmospheric distribution of trace gases and aerosols in a mountainous city. We present initial results from long-term operations and first highlights from two intensive operational phases, showing that 1) the exchange of greenhouse gas emissions is dominated by anthropogenic activities and is driven by location-specific venting of street canyon air; 2) foehn events significantly perturb the photostationary state indicative for an extensive and rapid airmass exchange of the valley atmosphere; 3) the temporal distribution of pollutants is often decoupled from their emissions and primarily modulated by mountain boundary layer dynamics; 4) we can detect a large number of volatile chemical products in the urban atmosphere, which can be used to fingerprint anthropogenic emission sources; and 5) the first urban carbonyl sulfide (COS) flux measurements point toward anthropogenic emission sources.
Reduction of Bias from Parameter Variance in Geophysical Data Estimation: Method and Application to Ice Water Content and Sedimentation Flux Estimated from Lidar
Authors: Bolot Maximilien , Fueglistaler Stephan 
Published: December 2019

Abstract
This paper addresses issues of statistical misrepresentation of the a priori parameters (henceforth called ancillary parameters) used in geophysical data estimation. Parameterizations using ancillary data are frequently needed to derive geophysical data of interest from remote measurements. Empirical fits to the ancillary data that do not preserve the distribution of such data may induce substantial bias. A semianalytical averaging approach based on Taylor expansion is presented to improve estimated cirrus ice water content and sedimentation flux for a range of volume extinction coefficients retrieved from spaceborne lidar observations by CALIOP combined with the estimated distribution of ancillary data from in situ aircraft measurements of ice particle microphysical parameters and temperature. It is shown that, given an idealized distribution of input parameters, the approach performs well against Monte Carlo benchmark predictions. Using examples with idealized distributions at the mean temperature for the tropics at 15 km, it is estimated that the commonly neglected variance observed in in situ measurements of effective diameters may produce a worst-case estimation bias spanning up to a factor of 2. For ice sedimentation flux, a similar variance in particle size distributions and extinctions produces a worst-case estimation bias of a factor of 9. The value of the bias is found to be mostly set by the correlation coefficient between extinction and ice effective diameter, which in this test ranged between all possible values. Systematic reporting of variances and covariances in the ancillary data and between data and observed quantities would allow for more accurate observational estimates.

AbstractTwo questions motivated this study: 1) Will meteorological droughts become more frequent and severe during the twenty-first century? 2) Given the projected global temperature rise, to what extent does the inclusion of temperature (in addition to precipitation) in drought indicators play a role in future meteorological droughts? To answer, we analyzed the changes in drought frequency, severity, and historically undocumented extreme droughts over 1981–2100, using the standardized precipitation index (SPI; including precipitation only) and standardized precipitation-evapotranspiration index (SPEI; indirectly including temperature), and under two representative concentration pathways (RCP4.5 and RCP8.5). As input data, we employed 103 high-resolution (0.44°) simulations from the Coordinated Regional Climate Downscaling Experiment (CORDEX), based on a combination of 16 global circulation models (GCMs) and 20 regional circulation models (RCMs). This is the first study on global drought projections including RCMs based on such a large ensemble of RCMs. Based on precipitation only, ~15% of the global land is likely to experience more frequent and severe droughts during 2071–2100 versus 1981–2010 for both scenarios. This increase is larger (~47% under RCP4.5, ~49% under RCP8.5) when precipitation and temperature are used. Both SPI and SPEI project more frequent and severe droughts, especially under RCP8.5, over southern South America, the Mediterranean region, southern Africa, southeastern China, Japan, and southern Australia. A decrease in drought is projected for high latitudes in Northern Hemisphere and Southeast Asia. If temperature is included, drought characteristics are projected to increase over North America, Amazonia, central Europe and Asia, the Horn of Africa, India, and central Australia; if only precipitation is considered, they are found to decrease over those areas.
The Decadal Reduction of Southeastern Australian Autumn Rainfall since the Early 1990s: A Response to Sea Surface Temperature Warming in the Subtropical South Pacific
Authors: Lin ZhongDa , Li Yun , Liu Yong , Hu AiXue 
Published: December 2019

AbstractRainfall in southeastern Australia (SEA) decreased substantially in the austral autumn (March–May) of the 1990s and 2000s. The observed autumn rainfall reduction has been linked to the climate change–induced poleward shift of the subtropical dry zone across SEA and natural multidecadal variations. However, the underlying physical processes responsible for the SEA drought are still not fully understood. This study highlights the role of sea surface temperature (SST) warming in the subtropical South Pacific (SSP) in the autumn rainfall reduction in SEA since the early 1990s. The warmer SSP SST enhances rainfall to the northwest in the southern South Pacific convergence zone (SPCZ); the latter triggers a divergent overturning circulation with the subsidence branch over the eastern coast of Australia. As such, the subsidence increases the surface pressure over Australia, intensifies the subtropical ridge, and reduces the rainfall in SEA. This mechanism is further confirmed by the result of a sensitivity experiment using an atmospheric general circulation model. Moreover, this study further indicates that global warming and natural multidecadal variability contribute approximately 44% and 56%, respectively, of the SST warming in the SSP since the early 1990s.
Behavioural activation treatment for depression in individuals with neurological conditions: a systematic review
Authors: Oates Lloyd L , Moghaddam Nima , Evangelou Nikos , das Nair Roshan 
Published: December 2019

Objective: To evaluate the effectiveness of behavioural activation interventions for people with neurological conditions with comorbid depression, and explore content and adaptations. Data sources: PsycINFO, MEDLINE, CINAHL, AMED, and EMBASE databases were searched on the 19 November 2019. Reference lists of selected full-texts were screened by title. Review methods: We included peer-reviewed studies published in English that used behavioural activation for treatment of depression in adults with a neurological condition. Single-case reports, reviews, and grey literature were excluded. Methodological quality was assessed by two authors independently, and quality was appraised using Critical Appraisal Skills Programme checklists. Results: From 2714 citations, 10 articles were included comprising 590 participants. Behavioural activation was used to treat depression in people with dementia ( n = 4), stroke ( n = 3), epilepsy ( n = 1), Parkinson’s disease ( n = 1), and brain injury ( n = 1). Sample size ranged from 4 to 105 participants. There were seven randomized controlled studies; however, no studies compared behavioural activation to an alternative psychological therapy. The effect sizes varied between small and large in the studies where effect size could be calculated ( d  = 0.24–1.7). Methodological quality of the included studies was variable. Intervention components were identifying and engaging in pleasurable activities, psychoeducation, and problem-solving. Adaptations included delivering sessions via telephone, delivering interventions via primary caregivers, and giving psychoeducation to caregivers. Conclusion: The effectiveness of behavioural activation in randomized controlled trials varied from small to large ( d  = 0.24–1.7) in reducing depression. The content of behavioural activation was comparable to established treatment manuals. Adaptations appeared to support individuals to engage in therapy.
