Characteristics and attribution of basic volcanic rocks in Liyuan-Labai township area, Yunnan Province
-
摘要:
云南西北部爪子—梨园—拉柏乡一线岀露有带状分布的基性火山岩，前人对该套火山岩的归属意见不同。调查研究显示，该套火山岩分布于扬子陆块最西缘，主要由橄榄玄武岩、辉斑玄武岩、火山角砾岩等组成，岩石发育有枕状构造和柱状节理构造，显示出水陆交互的喷发环境；岩石地球化学表现出富碱、低钾、高钛、轻稀土强烈富集、富集大离子亲石元素和高场强元素的特征；该带火山岩总体与云南西北部丽江—宾川地区二叠纪峨眉山玄武岩具有相似的特点，应归属于丽江地层分区的峨眉山玄武岩组。此外，在该套火山岩地层中下部的生物碎屑灰岩夹层中获取了一批生物化石，经鉴定时代为早—中二叠世，说明该套基性火山岩可能形成于早—中二叠世。
Abstract:There are basic volcanic rocks with banded distribution in the Zhuazi-Liyuan-Labai township area of Northwest Yunnan Province.Previous views concerning the attribution of basic volcanic rocks are controversial.According to the investigation and research, the basic volcanic rocks are distributed in the westernmost margin of the Yangtze Block, mainly composed of olivine basalt, pyroxene basalt, volcanic breccia, et. The rocks have pillow structure and columnar joint, showing the eruption environment of water land interaction; the petrological geochemistry shows enriched alkali, low potassium, high titanium, enriched LREE, enriched LILE and enriched HFSE characteristics; the basic volcanic rocks in this area are generally similar to the Permian Emeishan basalt in Lijiang-Binchuan area of northwest Yunnan Province, and belong to the Emeishan basalt formation in Lijiang stratigraphic regionalization.In addition, a number of biological fossils were obtained from the bioclastic limestone intercalations in the middle and lower part of the basic volcanic rocks.The age is identified as Early—Middle Permian, which shows that the basic volcanic rocks were formed in the Early—Middle Permian.
