Akita University SEG Student Chapter: Kitakami Area of Iwate Prefecture, JapanIn September 2022, the Akita University SEG Student Chapter(AU-SEGSC) organized a three-day field excursion to visit six
separate sites within the Kitakami region of Iwate Prefecture,
Japan. Some of the best-preserved and most coherent recordsof the evolution of the Japanese island arc predating the opening of the Sea of Japan are contained within geologic units
exclusive to this area.
The sites that were visited include the Kuji Amber Museum,the Noda Tamagawa metamorphosed stratabound Mn deposit,
the Ryusendo limestone caves, Jodogohama adakitic rhyolite
outcrop near Miyako City, the Tamayama pegmatite veinhosted Au deposit, and the Kamaishi Fe-Cu skarn deposit andmine. The theme of the excursion centered on field study ofskarn and orogenic Au deposits in the Kitakami region of NE
Honshu and its associated magmatic, hydrothermal, and metamorphic activities related to the Paleozoic-Mesozoic evolutionof the Japanese island arc. It was extremely interesting to learn
about the varied geology at each site and the different styles ofmineralization.
The field excursion had 20 participants consisting of 18
student members currently pursuing M.Sc. and Ph.D. research
projects related to economic geology and was led by ourchapter advisors Yasushi Watanabe and Andrea Agangi of theFaculty of International Resource Sciences, Akita University.
The AU-SEGSC is deeply grateful to the Stuart R. Wallace FundGroup photo taken during field study of the exposed skarn mineralization at the Shinyama deposit, Kamaishi.

and Akita University for the immense support given to makethis field excursion possible. For a full detailed report of all thesites visited on our field excursion please visit www.segweb.org/studentchapters.

The SEG Student Chapter of Montanuniversität Leoben conducted a field trip to Cyprus from September 19 to 28, 2022.
Twelve student members from the student chapter participated and were guided by SEG Fellow Johann G. Raith andRonald Bakker from Montanuniversität Leoben as well as byMontanuniversität Leoben Student Chapter field trip participants at
the Agrokipia mine (copper and sulfur production from 1952 to 1971)
with weathered/altered pillow basalts in the background.

colleagues from the Geological Survey of Cyprus. The aimof this trip was to study the world-famous Troodos ophiolitecomplex and its mineral resources—i.e., VMS, podiform chromite, and asbestos deposits. In addition, the Circum-Troodos
sedimentary sequences, which have potential for industrial
minerals (e.g., bentonite, gypsum), were visited.
The trip started with an introduction at the Troodos
UNESCO Global Geopark Visitor Centre. The first two daysfeatured an overview about the Troodos ophiolite complex
and the overlying sedimentary sequences. On the following days the group visited the lower ophiolite sequence(ultramafics with podiform chromite bodies; plutonicsequence) and the upper volcanic sequence (sheeted dikes,pillow lavas, VMS deposits). The abandoned copper mines
at Skouriotissa (operated by Hellenic Minerals until 2019),
Agrokipia, Mathiatis, and Kikkinovounaros allowed us tostudy the relationship of VMS (Cu-Zn ± Au) mineralization
and alteration to host rocks and geologic structures, as wellas aspects of ancient to recent mining and metallurgy. Trips
to the Mamonia Complex and Arakapas fault zone served tocomplete our understanding of the complex geologic evolution of Cyprus. We thank SEG for financial support throughthe Stewart R. Wallace Fund.
