Publikováno v: PeerJ, Vol 7, p e7875 (2019)

Preserved labile tissues (e.g., skin, muscle) in the fossil record of terrestrial vertebrates are increasingly becoming recognized as an important source of biological and taphonomic information. Here, we combine a variety of synchrotron radiation te

Zinc, copper, and strontium isotopic variability in the Baiyangping Cu–Pb–Zn–Ag polymetallic ore field, Lanping Basin, Southwest China

Autor: Ian M. Coulson, Guoxiang Chi, Ruizhong Hu, Shen Liu, Xian-Wu Bi, Caixia Feng

Publikováno v: Acta Geochimica. 40:557-574

The Baiyangping Cu–Ag polymetallic ore district is located in the northern part of the Lanping-Simao foreland fold belt, between the Jinshajiang-Ailaoshan and Lancangjiang faults, and the deposit can be divided into eastern and western ore zones. B

Lithological and Si–O–S isotope geochemistry: constraints on the origin and genetic environment of the selenium (Se)-rich siliceous rocks in Enshi, Hubei Province, China

Autor: Shen Liu, Ian M. Coulson, Caixia Feng

Publikováno v: Acta Geochimica. 40:89-105

Se-rich black rock series of the Middle and Late Permian system is widely distributed in Enshi Prefecture with an exposed area of 850 km2, among which the unique Yutangba black rock series independent selenium deposit with industrial mining significa

Zircon U–Pb geochronology, whole-rock geochemical, and Sr–Nd–Pb isotopic constraints on the timing and origin of Permian and Triassic mafic dykes from eastern North China Craton

Autor: Yan Fan, Shen Liu, Huibo Zhao, Xiaoqing Chen, Caixia Feng, Ian M. Coulson, Yuhong Yang

Publikováno v: Acta Geochimica. 39:862-886

This work reports an important episode of extensional, mafic magmatism that impacted the North China Craton (NCC) during the Permo-Triassic and influenced the evolution of this Craton. We sampled 30 representative mafic dykes cropping out in eastern

Zircon U–Pb dating, geochemical, and Sr–Nd–Pb–Hf isotopic constraints on the age and origin of intermediate to felsic igneous rocks at South Altyn, Xinjiang, China

Autor: Shen Liu, Ian M. Coulson, Huibo Zhao, Yan Fan, Xiaoqing Chen, Caixia Feng, Yuhong Yang

Publikováno v: Acta Geochimica. 39:698-716

As a part of a giant trending fault system in the Asian continent and one where a strong zone of left strike-slip fault is present, the Altyn Orogenic belt (AOB) has become an important focus for research. Magmatic rocks are widely distributed across
