摘要
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。
Since the Cenozoic,affect ed by the co llision and compr essio n of the Indian plate and Eurasian plate,the T ibetan Plateauhad a stro ng uplift,and the g eolog ical str ucture o f Qing hai chang ed dramatica lly.As a result o f this specia l g eolo g ical pro cess,magmatic r ocks a re w idely distr ibuted all o ver the pro vince since the IndoYanshanian perio d,the distr ibution o f activ e struc2tur es has changed since the late Cenozoic,and the unique g eothermal and g eo lo gical conditions of Qing hai hav e been formed.Inthis paper,acco rding to the analysis of the g eothermal mo dels o f H DR r eso ur ces disco vered at home and abro ad,co nsider ing thegeothermal and g eolog ical backg round of Qinghai and the H DR resource types and distributio n patterns,w e conducted a brief a2nalysis on the feat ur es o f different ty pes o f H DR resources in Qing hai.We fo cused on t he intraplat e active tectonic zone t ypeHDR resources and the sedimentar y basin ty pe HDR r eso ur ces.On this basis,w e studied the differ ent g eo thermal mo dels ofHDR resour ces,and compar ed t he formation mechanisms of different t ypes of HDR r eso ur ces.This research pro vides a basis forfur ther ex plor ation and develo pment of H DR resources in Qing hai.
