Genesis type of ore deposits indicated by trace elements of chalcopyrite
地质科技通报, 2023 Trace elements of metallic minerals are important to constrain the formation processes and genetic types of ore deposits. Trace elements have been mainly focused on pyrite, magnetite, and sphalerite but have rarely been applied to chalcopyrite. To reveal

Journal of Geophysical Research: Solid Earth, Volume 124, Issue 11, Page 10655-10671, November 2019., 2019 Abstract The Mount Isa Province in northern Australia is one of the world's most strongly endowed regions for base metals and host to major iron–oxide–copper–gold (IOCG) deposits. The Carpentaria conductivity anomaly at the eastern margin of the province is a major electrical conductivity structure of the Australian continent.

Withdrawn: Allanites in the Sin Quyen IOCG deposit, North Vietnam
, 2020 Allanite minerals are the principal host of REEs in the Sin Quyen, Iron Oxide Copper Gold (IOCG) type deposit. The studied allanites have concentrations of: REE (14-27 wt%), Ca (9-16 wt%), Al (8-19 wt%), Si (26-34 wt%) and Fe (12-21 wt%). Two populations of allanite are documented, the first is texturally older probably related to the Ca-K alteration ...

Geofluids, Volume 2018, Issue 1, 2018., 2018 New stable isotopic data from mineral separates of albite, scapolite, amphibole, quartz, and calcite of metasomatic rocks (Bamble lithotectonic domain) give increased knowledge on fluid type, source, and evolution during metamorphism. Albite from a variety of albitites gives δ18OSMOW values of 5.1–11.1‰, while quartz from clinopyroxene‐bearing albitite

Geoscience Data Journal, Volume 13, Issue 1, January 2026.We build a new, open‐source global copper deposit dataset (GCDD), facilitating AI‐driven data analysis for exploration targeting and improving our understanding of copper mineralizing systems and their mappable expressions. The GCDD hosts information about 1483 copper deposits worldwide, capturing key deposit attributes such as location, genetic type ...

Journal of Geological Research, Volume 2014, Issue 1, 2014., 2014 The Qatruyeh iron deposits, located on the eastern border of the NW‐SE trending Sanandaj‐Sirjan metamorphic zone, southwest of Iran, are hosted by a late Proterozoic to early Paleozoic sequence dominated by metamorphosed carbonate rocks. The magnetite ores occurred as layered to massive bodies, with lesser amounts of disseminated magnetite and hematite‐
