巢湖石特征形成机理与开发研究

巢湖石是一种独特的旅游地质资源,巢湖地区独特的地质地理环境造就了丰富多样的巢湖石资源.本文从本地区的地质构造特征和环境条件入手,对巢湖石的产地与分布、特征与形成机理、分类以及市场与开发现状进行了研究.研究认为,巢湖石主要是石炭纪、二叠纪以及三叠纪等地质时期形成的碳酸盐岩,在漫长的地质历史过程中,经过风化、淋滤、剥蚀、溶蚀等外力地质作用,被雕琢而成的造型奇特的自然艺术品,以其形体上的差异、奇筋异脉、丰富的化石、独特的结核以及圆润的孔洞而区别于其它观赏石.巢湖石开发历史悠久,分布广、品种多、成因类型齐全,但勘查评价程度低、形成规律研究不够、开发过程中对资源价值认识不够、造成破坏和浪费,因此要加强管理、保护性开采,特别是加强地质勘查评价、形成机理与规律研究.

On the Features and Exploitation of Chaohu Stone

Based on the analysis of regional environment and its geological structural characteristics in Chaohu of Anhui Province,a study has been made on the features,distribution and market present status of Chaohu stone.The result showed that:(1) The Chaohu stone forms in the Carboniferous Triassic carbonate rocks,especially the Permian chi Hsia limestone.Under external geology functions, it became a natural art ware,which can embellish the botanical garden.(2) The Chaohu stone not only has the Taihu stone's marvelous modeling,but also has its unique characteristics,such as its different physique,the wonderful muscle, the rich fossil,the unique tuberculosis as well as the clear hole.(3) Although the Chaohu stone is distributed extensively,and the types of Chaohu stone and its genesis are varied,they have not been brought into mineral administration. So we must pay more attention to the value of Chaohu stone resource,especially the geological investigation and its formation mechanism research.
