Scavenging and release of REE and HFSE by Na-metasomatism in magmatic-hydrothermal systems

Autor: Wu-Bin Yang, He-Cai Niu, Ning-Bo Li, Pete Hollings, Shannon Zurevinski, Roger H. Mitchell

Publikováno v: Fundamental Research, Vol 4, Iss 2, Pp 315-323 (2024)

Exploitable or potentially exploitable deposits of critical metals, such as rare-earth (REE) and high-field-strength elements (HFSE), are commonly associated with alkaline or peralkaline igneous rocks. However, the origin, transport and concentration

Geochemistry and Isotopic Characteristics of Apatite and Zircon From Late Jurassic Granites in the Jiaobei Terrane, East China: Implications for Petrogenesis and Geodynamic Setting

Autor: Xiancheng Mao, Xin Qu, Zhankun Liu, Jixian Huang, Pete Hollings, Peijie Du, Haibin Yang

Publikováno v: Frontiers in Earth Science, Vol 10 (2022)

The North China Craton (NCC) was stable for more than 2.0 Gyr before a Jurassic–Cretaceous large-scale lithospheric thinning event, but the geodynamic setting during the early phases (Late Jurassic) of NCC reworking remains controversial. We presen

Pyrite geochemistry in a porphyry-skarn Cu (Au) system and implications for ore formation and prospecting: Perspective from Xinqiao deposit, Eastern China

Autor: Xin Xiao, Taofa Zhou, Pete Hollings, Noel C. White, Yu Fan, Lejun Zhang, Bin Fu

Publikováno v: American Mineralogist. 108:1132-1148

Stratabound ore has been recognized as an end-member of porphyry copper systems, but pyrite chemistry has not been widely applied to linking stratabound ore with the related porphyry and skarn system. Stratabound ore is commonly developed around porp

Dating rare earth element enrichment in deep-sea sediments using U-Pb geochronology of bioapatite

Autor: Dengfeng Li, Jinzhou Peng, David Chew, Yongjia Liang, Pete Hollings, Yu Fu, Yanhui Dong, Xiaoming Sun

Publikováno v: Geology. 51:428-433

Deep-sea sediments rich in rare earth elements and yttrium (REY) are promising mineral resources that are believed to be associated with the burial of fish debris. However, the nature of the REY enrichment is poorly understood, in part due to a lack

The ~1.1 Ga St. Ignace Island complex, Northern Ontario, Canada: Evidence for magma mixing and crustal melting in the generation of Midcontinent Rift-related bimodal magmas and implications for regional metallogeny

Autor: Pete Hollings, Jacob Hanley, Mark Smyk, Larry Heaman, Brian Cousens, Zoltán Zajacz

Publikováno v: Journal of Petrology.

The St. Ignace Island complex in Northern Ontario is a package of dominantly felsic rocks emplaced within the upper portions of the Osler Volcanic rocks of the ~1.1 Ga Midcontinent Rift System. The Osler volcanic rocks are predominantly tholeiitic ba

Two stages of porphyry Cu mineralization at Jiru in the Tibetan collisional orogen: Insights from zircon, apatite, and magmatic sulfides

Autor: Xiang Sun, Jun Deng, Yongjun Lu, Xiaobo Si, Pete Hollings, M. Santosh, Qiang Li, Xu Zheng

Publikováno v: GSA Bulletin.

Continental collision−related porphyry copper (Cu) deposits provide significant global copper resources, but their genesis remains controversial because it is not clear whether remelting of remnant arc-derived lower-crustal Cu-rich cumulates is cri

Geology of the Mesoproterozoic Pillar Lake Volcanics and Inspiration Sill, Armstrong, Ontario: evidence of early Midcontinent Rift magmatism in the northwestern Nipigon Embayment

Autor: Wouter Bleeker, Robert Cundari, Michael R.M. Easton, Mark Smyk, Pete Hollings, Michael A. Hamilton

Publikováno v: Canadian Journal of Earth Sciences. 58:1116-1131

The Midcontinent Rift System of North America is a ∼1.1 Ga large igneous province comprising mainly flood basalts and intrusive rocks. We present new data for the Pillar Lake Volcanics and Inspiration Sill from the northern edge of the Midcontinent

A 50 m.y. melting model for the rare metal−rich Koktokay pegmatite in the Chinese Altai: Implications from a newly identified Jurassic granite

Autor: Jinsheng Han, Zhenhua Zhao, Pete Hollings, Huayong Chen

Publikováno v: GSA Bulletin.

The petrogenesis of the world famous Koktokay No. 3 pegmatite in the Chinese Altai Mountains is still enigmatic due to its superenrichment of rare metals and the apparent absence of a parental granite. We present results from a granite apophysis that

Apatite Texture, Composition, and O-Sr-Nd Isotope Signatures Record Magmatic and Hydrothermal Fluid Characteristics at the Black Mountain Porphyry Deposit, Philippines

Autor: Ming Jian Cao, Kezhang Qin, Pete Hollings, Brent I.A. McInnes, Noreen J. Evans, David R. Cooke

Publikováno v: Economic Geology. 116:1189-1207

The trace elemental and isotopic signatures in apatite can be modified during hydrothermal alteration. This study investigates the suitability of apatite as an indicator of the source, chemistry, and evolution of magma and hydrothermal fluids. In sit
