滇西北三江并流带观赏石资源及开发研究

观赏石是一种商品性旅游地质资源．滇西北三江并流带独特的地质地理环境造就了丰富多样的观赏石资源，但目前尚缺乏系统研究．为适应滇西北旅游开发的需要，本文对三江区观赏石资源的成因、分类、形态特征、地理分布、规模及开发利用价值等进行了研究．主要根据形态特征，把三江区观赏石资源划分为狭义观赏石、宝玉石和彩石、观赏石材及观赏矿石矿物四大类，重点研究了金沙江蛇绿岩地质事件石、三江石、宝玉石和彩石的成因、形态特征及地理分布，并新发现了两类造型石——金山石和麻花石．并就观赏石资源的保护、科研评估及旅游开发等方面提出了对策．

Study on the Resources and Exploitation of Ornamental Stones in the Three-Parallel-River Belt,NW Yunnan

Ornamental stones are a commodity and tourism geology resources. The unique geological and geographical environment brings up the rich and varied resources of ornamental stones in Three-quarrel-river belt of NW Yunnan. But it is short of systematic studies at present. A study has been made on the cause, classification , form character, geographical distribution, scale and the exploitation value of ornamental stones in NW Yunnan . It is divided into four types: narrow sense ornamental stones, gem-jade stone and color stone, ornamental rock, ornamental ore and mineral based on the form character. It has been studied on the cause, form character and the geographical distribution of geological event stone of Jinshajiang ophiolite, Sanjiang stone, gem-jade stone and color stone. Two new types of ornamental stone, Jinshan stone and Mahua stone have been discovered. And the strategies of protection, scientific study and evaluation, tourism exploitation of ornamental stones are also put forward.
