本文是指那些在时间和空间上与中酸性侵入岩无关或远离这些岩体接触带的夹于正常沉积岩或火山沉积岩中的层状夕卡岩.这种夕卡岩一般厚度不大,单层厚度数至数十米,呈多层出现.与这套岩层相伴随往往有钨、钼、铁、铜、铅、锌、金等矿产. 目前所知,这种层控夕卡岩的产出时代和层位很广,从元古代到中生代均有分布.由老到新,产于元古代的有江西九岭杨梅尖山的层控夕卡岩金-锑-钨矿床;产于中寒武统的有云南东南部文山地区的田蓬组层状夕卡岩白钨矿床(其规模中至大型,已知单个矿体长度1000～3000米,厚度1～5米,WO_3含量0.11～1.173%,含Sn0.048～0.09%)和都龙群大理岩片岩层中的层控夕卡岩大型浸染状Sn、Zn、Cu多金属
This paper refers to stratiform skarns sandwiched between normal sedimentary rocks or volcanic sedimentary rocks that are not related in time and space to or associated with these intrusive rock intrusions, Thickness to tens of meters, appeared in multiple layers with the rock formation are often accompanied by tungsten, molybdenum, iron, copper, lead, zinc, gold and other minerals.As far as is known, this layer control skarn output Era and strata are widely distributed from Proterozoic to Mesozoic, and from old to new, the metamorphic skarn gold-antimony-tungsten deposit, dating from the Yuanmei and Yangmei Jianshan in Jiangxi Province, There are the Tianpeng Formation scheelite scheelite deposits in the Wengshan area in the southeastern part of Yunnan (the scale is large to large, and the length of a single ore body is known as 1000-3000 m, the thickness of 1-5 m, the WO 3 content of 0.11-1.173% , Containing Sn0.048 ~ 0.09%) and the Du Longqun marble sheet schist layers stratified skarns large disseminated Sn, Zn, Cu polymetallic
