中条山胡家峪—上玉坡背斜核部“绛县群变酸性火山岩”的新认识

NEW RECOGNITION ON THE"META-ACID VOLCANIC ROCKS OF THE JIANGXIIAN GROUP"IN THE CORE REGION OF THE HUJIAYU-SHANGYUPO ANTICLINE OF THE ZHONGTIAO MOUNTAINS

摘要: 中条山胡家峪—上玉坡背斜核部分布的所谓“绛县群变酸性火山岩或变富钾流纹岩。”通过对其岩相学、岩石学以及构造地质学的研究,作者认为是中条中后期浅成侵入的霏细斑岩体,不能与北部铜矿峪地区绛县群变酸性火山岩视为同一的地层单元。

Abstract: Through a study of the petrography. petrology and structural geology, the "meta-acid volcanic rocks or metapotassic rhyolite" over the core region of the Hujiayu-Shangyupo anticline are considered to he hypahyssal felsitic porphyry bodies intruded in the middle-late Zhongtiaoan stage and cannot be regarded as the same stratigraphic unit as meta-acid volcanie rocks of the Jiangxian Group in the Tongknangyu area in the northern part of the area.
