title: Lithofacies, paleoenvironments and sequence stratigraphy of the Late Oligocene Aotea Formation (Te Kuiti Group), central-western North Island, New Zealand

authors: Kamp, Peter J.J.

abstract: This report presents a comprehensive facies and sequence stratigraphic analysis of the Late Oligocene Aotea Formation within the Late Eocene – Earliest Miocene Te Kuiti Group in the Waikato-King Country Basin in central-western North Island, New Zealand. The Aotea Formation is a mixed carbonate-siliciclastic succession with four facies associations: limestone (Waimai Limestone Member), calcareous sandstone (Hauturu Sandstone Member, Kihi Sandstone Member), calcareous siltstone (Patikirau Siltstone Member) and chemogenic facies (upper parts of Kihi Sandstone Member, Patikirau Siltstone Member and Waimai Limestone Member). Theses facies are established from field descriptions supplemented by laboratory textural and petrographic data and are inferred to have accumulated in different sectors of a shelf environment. The Aotea Formation comprises one sequence for which key surfaces and systems tracts are described and interpreted. The lower sequence boundary is a wave-planed surface. It, together with the subsequent onlap deposits represent a marked basinward shift in the position of coastal onlap arising from basin inversion focussed along the western margin of the basin, followed by marked subsidence in the northern part of the basin.

title: Nickel(II) complexes of di- and tri-substituted thiourea mono- and di-anions

authors: Yuen, Ho Ying

subjects: nickel complexes

abstract: Reaction of nickel(II) acetate, 1,2-bis(diphenylphosphino)ethane (dppe), and a di- or tri-substituted thiourea R¹NHC(S)R²R³ (R³ = H or alkyl) with trimethylamine in hot methanol gave cationic nickel(II) complexes containing N,S-chelated thiourea monoanion ligands [Ni{SC(NR²R³)NR¹}(dppe)]⁺ , which can be readily isolated as their BPh₄⁻ salts. The X-ray crystal structure of [Ni{SC(NMe₂)NPh}(dppe)]⁺BPh₄⁻ is reported.

title: He Matapihi Mā Mua, Mō Muri: The Ethics, Processes, and Procedures Associated with the Digitization of Indigenous Knowledge—The Pei Jones Collection

authors: Whaanga, Hēmi

abstract: The digital era has transformed how people live their lives and interact with the world and knowledge systems around them. In Aotearoa/New Zealand a range of initiatives incorporating Indigenous knowledge have been implemented to collect, catalog, maintain, and organize digital objects. In this article, we report on the ethics, processes, and procedures associated with the digitization of the manuscripts, works, and collected taonga (treasures) of the late Dr. Pei Te Hurinui Jones—and describe how it was transformed into a digital library. It discusses the decision-making processes and the various roles and responsibilities of the researchers, family members, and institute in this process.
