青藏高原东北缘海原-六盘山断裂带现今地壳应力环境的数值分析

海原-六盘山断裂是青藏高原东北缘的大型边界断裂带,是中国大陆典型的地震危险区。地壳构造加载特征的定量研究有助于分析区域孕震环境,参考青藏高原东北缘GPS形变和岩石圈精细结构等资料,本文建立海原-六盘山断裂带周缘的三维岩石圈分层模型,分析现今构造加载作用下区域地壳形变和应力演化特征。数值计算结果显示:青藏高原东北缘现今处于以北东-南西向的水平挤压为主导和北西-南东向的水平引张的变形特征。青藏高原东北缘中-下地壳流变性质影响上覆脆性地壳应力环境,中地壳较低粘滞系数对应的模型地壳应力计算值与研究区实际地壳应力场相近。海原断裂中-西段构造加载作用显著,具有相对较高的库仑应力积累和最大剪应力分布;而六盘山断裂周缘地壳应力和最大剪应力小于海原断裂带。构造应力积累的空间分布差异说明六盘山断裂具有较弱的构造孕震环境,而研究区走滑型断裂的孕震加载作用显著。尽管六盘山处于较低的应力状态,但仍不能轻易忽视其长期存在的强震空区所暗示的发震潜力。

青藏高原北缘断裂擦痕的构造分析

通过大量断层擦痕数据计算机处理和野外地质观察，作者将青藏高原北缘上新世以来的脆性构造应力场分为２期；上新世－中更新世，主压应力近于Ｓ－Ｎ；中更新世至今，主压应力方位为ＮＥ向和ＮＷ向；最后对青藏高原北缘的地球动力学过程作了分析。

揭示地质现象的本质与核心

青藏高原的形成与演化是举世瞩目的现代地学前缘 ,岩石圈结构及其演变对于探讨高原隆升及其资源环境效应具有重要意义。多年来 ,对于青藏高原岩石圈结构的认识主要基于地球物理探测结果和地质研究 ,尚未发现深达地幔的物质。我们在西昆仑地区康西瓦新生代火山岩中首次发现了以含金云母方辉橄榄岩为主的深源包体 ,其主要组成矿物为橄榄石和斜方辉石 ,含有少量单斜辉石、尖晶石和金云母。橄榄岩具有平衡粒状变晶结构 ,部分橄榄石颗粒仍保留有扭折带。电子探针分析结果表明 ,尖晶石的x(Cr) /x(Cr +Al)变化为 2 5%～ 8% ,属于尖晶石铬铁矿系列。根据CarrollWebb和Wood(1986 )提出的温压图解 ,橄榄岩形成压力大致为16 0 0MPa ,约相当于深度 56km。据此 ,认为康西瓦新生代玄武岩中产出的橄榄岩包体系岩浆活动过程中从岩石圈地幔携带上来的幔源物质 ,对于探讨青藏高原北部的岩石圈结构及其演化具有重要意义。
