Hematite Formation During Skarn Mineralization in the Akatani Iron Deposit, Niigata Prefecture, Japan

Resource Geology, Volume 76, Issue 1, January/December 2026.
The Akatani Fe deposit in NE Japan has been regarded as a skarn deposit because iron‐oxide ores occur within marble‐hosted skarn near the Cretaceous Ninoujidake granite. U–Pb dating of fluorapatite in the skarn indicates that this skarn formed in the Late Cretaceous, contemporaneous with the granite.

Age and Origin of Mafic Dykes in the Mianhuakeng Uranium Deposit, South China: Tectonic and Metallogenic Implications

Minerals
The Mianhuakeng deposit, located within the Zhuguangshan batholith in the Nanling area, is currently recognized as the largest granite-related uranium deposit in China. A portion of the uranium ore bodies is spatially associated with NE-trending mafic veins within the granite. In this study, the field investigation, zircon U-Pb dating, S and Pb isotope

In-situ Micro-scale Pb Isotope Identification Characteristics of Metallogenic and Non-metallogenic Pyrites in Sandstone-type Uranium Deposits

, 2022
BACKGROUND Sandstone-type uranium deposits contain a large number of pyrites of different shapes and stages. It is difficult to accurately discriminate the pyrite formed before, during or after the metallogenic period solely by observation of pyrite ...

Detrital Zircon U-Pb Geochronology of the Dazhuyuan Formation in Northern Guizhou: Implications for Bauxite Mineralization

Yankuang ceshi, 2013
The Late Carboniferous Dazhuyuan Formation, an important bauxite bearing bed, lies along the Northern Guizhou-Southern Chongqing formation. For tracing the material source of the bauxite, U-Pb dates on detrital zircon of aluminous from Dazhuyuan bauxite ...

Petrogenesis and metallogenic implications for the Machang, Huangdaoshan, and Tuncang plutons in eastern Anhui: an integrated age, petrologic, and geochemical study

International Geology Review, 2017
The Tuncang–Chuzhou–Machang area (eastern Anhui province) is geologically located in the intersection between the Yangtze block and the Qinling–Dabie orogenic belt. Many Mesozoic plutons outcrop in this district that are Cu–Au prospective but inadequately studied. We report new LA-ICP-MS zircon U–Pb ages, petrologic, and whole rock geochemical data for

Petrogenesis of the Late Ordovician Penggongmiao biotite monzogranite in southern Hunan, south China: constraints from geochronology, geochemistry, and Sr–Nd–Hf isotopes

Frontiers in Earth Science
The Penggongmiao complex pluton, located in the Nanling metallogenic belt of South China, provides a critical record of Early Paleozoic (Caledonian) magmatism, but the genesis and mineralization potential of the biotite monzogranite of the pluton have ...
