The Confirmation of Yanshanian Biotite Granite in the Hehuaping Sn-Pb-Zn District, Southern Hunan Province, China
摘要
Abstract
The Wangxianling granite was emplaced at the Indosinian (Triassic) period. The previous research considered that the Hehuaping Sn-Pb-Zn deposit was an Indosinian deposit related to the Wangxianling pluton. Based on many years of investigation in the field and study of rocks from drilling holes, a buried pluton with lithological characteristics different from the Wangxianling granite was discovered in the Hehuaping district. A zircon U-Pb age of (157.1 ± 0.8) Ma for the coarse-grained biotite granite from drilling hole was obtained by La-MC-ICP-MS, which suggests an early Yanshanian (Jurassic) emplacement. This granite is characterised by A/CNK value of 1.02, total REE content of 357 x 10"*, LREE/HREE ratio of 2.83 and Zr+Nb+Ce+Y content of 398 x 10-6, on average. These features are similar to those of A-type granite and markedly different from those of the Wangxianling S-type granite. This Yanshanian granite, named as Hehuaping granite, has an affinity of the tin-bearing granites in the Nanling Range. Therefore, we argue that the Hehuaping Sn-Pb-Zn deposit is related to the Yanshanian buried Hehuaping pluton.关键词
