Kuroko Deposits of NE Japan: The Product of High‐Temperature, Shallow Felsic Volcanism in a Deepening Continental Rift

Terra Nova, EarlyView.
ABSTRACT The Hokuroku district of NE Japan hosts the type locality for Kuroko volcanic‐hosted massive sulphide (VHMS) deposits, which are the product of seafloor hydrothermal venting in a continental rift during the opening of the Sea of Japan in the Miocene.

Petrology and geochemistry of Late Proterozoic hornblende gabbros from southeast of Fariman, Khorasan Razavi province, Iran

Journal of Economic Geology, 2015
Introduction Hornblende-bearing gabbroic rocks are quite common in subduction-related magmatic suites and considered to represent magmatic differentiation process in arc magmas (Heliker, 1995; Hickey-Vargas et al., 1995; Mandal and Ray, 2012).

Mining an Anthropocene in Japan: On the making and work of geological imaginaries

Transactions of the Institute of British Geographers, EarlyView.
Short Abstract This article addresses how the lithic and the drift might be reworked as an Anthropocene material outside of a chronostratigraphy. Revisiting the finding of a floating fern fossil at the Hashima mine, we delve into a complex array of Geological imaginaries, and undertake our own speculative work.

An archean suture zone in the Tobacco Root Mountains? (1984) Evolution of Archean Continental Crust, SW Montana (1985) [PDF]

The Lake Plateau area of the Beartooth Mountains, Montana were mapped and geochemically sampled. The allochthonous nature of the Stillwater Complex was interpreted as a Cordilleran-style continental margin.

The Nitrogen Budget of Earth

, 2015
We comprehensively compile and review N content in geologic materials to calculate a new N budget for Earth. Using analyses of rocks and minerals in conjunction with N-Ar geochemistry demonstrates that the Bulk Silicate Earth (BSE) contains \sim7\pm4 ...

Petrogenesis of melanite-garnets in monzodiorites from SW of Jandaq (NW of Central-East Iranian Microcontinent)

Journal of Economic Geology
The Godar-e-Siah Eocene monzodiorite stock is located in the southwest of the Jandaq area (NE of Isfahan) and northwest of the Central-East Iranian Microcontinent (CEIM). The main minerals in these monzodiorites are plagioclase, K-feldspar, clinopyroxene,
