辽东半岛红色风化壳粒度分布特征浅析

LIAODONG PENINSULA RED WEATHERING CRUST CHARACTERISTICS OF PARTICLE SIZE DISTRIBUTION

运用贝克曼激光衍射粒度分析仪对辽东半岛大连市棋盘子村和龙王村的红色风化壳作粒度特征分析,粒度频率分布曲线的差异指示出两地风化壳风化程度较弱,风化不完全。结合X射线荧光光谱仪进行化学分析进一步探讨两地的风化特征,发现两地各自发育的母岩都具有不均一性,棋盘子村风化壳的发育与母岩具有同源关系,龙王村风化壳发育与母岩非同源。与南方红色风化壳比较,南方红色风化壳风化程度高于棋盘子村,且母岩具有均一性。

Analysis the granularity characteristics of red weathering crust in dalian＇s qipanzi and longwang village of liaodong peninsula by Beckman Laser diffraction particle size analyzer, and differences in size frequency distribution curve indicates the degree of weathering weathering crust of the two place is weak, weathered incomplete. Combined with X -ray fluorescence analysis to further investigate the chemical weathering characteristics of the two places, found that both their respective development of parent rock is uneven. Qipanzi village development of weathering crust have kinship with its parent rocks, but not longwang village. Compared with the southern red weathering crust, found that the weathering degree of southern red weathering crust is higher than qipanzi and longwang village, and the parent rock of southern is uniformity.
