青海省干热岩资源类型及典型地热模式

新生代以来,受印度板块与欧亚板块的碰撞挤压作用,青藏高原发生强烈的隆升,青海省地质构造发生巨大变化。在这一特殊的地质作用下,印支—燕山期以来岩浆岩广泛分布于全省,并造就了挽近期活动构造的展布变化及青海省特有的地热地质条件。本文根据国内外已发现干热岩资源类型成因模式分析,结合青海省地热地质背景、干热岩资源类型、分布规律等,简要分析了不同类型干热岩资源特征,重点分析讨论强烈构造活动带型和沉积盆地型干热岩资源,并在此基础上研究不同类型干热岩资源地热模式,比较不同干热岩资源形成机制之间的差异,为进一步勘查、开发青海省干热岩资源提供依据。

Research on the resource types and typical geothermal models of hot dry rock resources of Qinghai

Since the Cenozoic, affected by the collision and compression of the Indian plate and Eurasian plate, The Tibetan Plateau occurred a strong uplift, and the geological structures of Qinghai changed dramatically. In this special geological, magmatic rocks are widely distributed in the province since the Indo-Yanshanian, and created a pull distribution structure change activity and Qinghai unique geothermal geological conditions since Pull Recent. In this paper, according to the type of geothermal model on HDR resources which has been found at home and abroad, combining geothermal geological background, HDR resource types, distributions and etc, conducted a brief analysis on the different types of HDR resources feature of Qinghai. The discussion focused on the intraplate active tectonic zone type HDR resources and the sedimentary basin type HDR resources. On this basis, research on different geothermal models of HDR resources. The genetic mechanisms of different types of HDR resources are analyzed and compared. Provide the basis for further exploration and development of HDR resources in Qinghai.
