摘要:

从区域地质构造背景分析入手,在研究岩层建造、花岗岩带分布及深大断裂特征的基础上,利用构造形迹的几何参数、声发射测试、有限元数值模拟3种方法恢复了黑龙江省东部区中一新生代构造应力场,提出了研究区的旱白垩世构造应力场呈西、中、东应力不均衡分布的特征、晚白垩世及第三纪构造应力场为旋扭性特征、新第三纪构造应力场为北西一南东向挤压特征的新认识。通过分析区域动力环境,总结研究区构造发生、发展及演化特点,为该区成矿系统研究提供了构造资料。

关键词: 黑龙江, 动力学环境, 构造应力场

Abstract:

Researched to start from geological—structural background in Heilongjang eastern area,base rockconstructing,granite distribution,deep—large break characteristic is analyzed,Mesozoic—Neozoic Structural stress—field is restored bv using the three method—geometric parameter of structural formative—tracks,sonic—discharge determine and limiter dimension nuneric imitate.A new viewpoint the early cretaceous structural stress—fields are unproportional in westem zone.middle zone,eastern zone,that late cretaceous and old tertiary structural stress—fields are gY
ral—torsional and that new tertiary structural crush—stress distributed at northwest~southeast direction is suggested.The aera s geological dynamic condition is analyzed; structural occurred,developed and evolved special feature is summed up.Structural information iS provided for analyzing form —mine in the area.

Key words: Hei longjang, Dynamic condition, Structural stress—field
