福建行洛坑钨矿典型实物标本采集与保管意义初探

摘要

行洛坑斑岩型黑白钨（钼）矿位于福建省宁化县，矿床规模属特大型，累计探明储量（WO3）30．43万 t，并伴生有钼锡铋及铌钽锂铍铷等多种有益元素。中国地质调查局实物资料中心在福建行洛坑钨矿的6个采样点采集了10块典型系列标本，同时采集了一块大型钨矿石标本，并收集了相关的成果资料。本文在介绍行洛坑钨矿成矿地质背景、矿床成因的基础上，通过不同岩性标本的采集，总结了典型实物标本采集的方法，并对其在实物地质资料中的保管意义进行了初探。%The Xingluokeng porphyry tungsten deposit is a large scale deposit located in Ninghua Fujian Province,whose total proven reserves (WO3 )are 30.43 million ton.It Associated Mo,Sn,Bi,Nb,Ta,Li,Rb and other beneficial elements rubidium.Cores and samples centre of CGS collected 10 blocks of typical series of specimens and a large-scale tungsten ore samples on 6 sampling points of Fujian Xingluokeng tungsten deposit,and also collected other relevant materials.Based on the geological background and genesis of mineralization,and through colleting the specimen of different rock,this paper summarizes the methods of collection of typical specimens and discusses the preservation significance of the specimen.
