The analysis of weathering crust characteristic of lower Permian Kalagang group in Malang sag, Santanghu basin suggests that the paleo-weathered crust includes weathering clay ground, strong weathering rubble layer, weak, weathering block-stone layer and unweathered rock layer in vertical and was distributed under the unconformity interface and presented in planar manner horizontally.

对三塘湖盆地马朗凹陷下二叠统卡拉岗组风化壳特征的分析，认为古风化壳纵向上分为风化粘土层、强风化碎石层、弱风化块石层以及未风化岩石层等，平面上呈面状分布于不整合界面之下，剖析该区古风化壳成藏地质条件和构造演化，探讨了可能发育油气藏类型及与风化壳的关系，并指出了该区下一步下二叠统卡拉岗组有利的勘探目标是在P2t剥蚀线与P1k剥蚀线之间范围内，其次为卡拉岗组剥蚀线以东地区。

The surface soil and the unconsolidated mantle rock beneath it form only a thin venner.

Then, basing on the practical problems of the studying area-the thickness of aquifer is little, the capability of depositing water is finite, the Quaternary loose stratum directly superimposes the bedrock strong breeze girdle, the writer thinks it is difficult to answer for the water use of the polyvinyl chloride project by the centralized tube well pumping.

根据研究区含水层厚度小、储水能力差，第四系松散层直接叠加在基岩强风化层之上的具体特点，认为管井集中开采难以满足聚氯乙烯工程的需水量要求，采用集水廊道最大限度地激发河流对地下水的补给，是在这一地区获得较大开采量的有效方式。

Recent developments in the research on the geology and geochemistry of the newly-discovered clayey breccias at the lop of the Xiaochaka Formation in the Juhuashan, Xiaochaka and Shishuihe areas, Qiangtang Basin, northern Tibet have disclosed that mineral compositions, textures and structures, occurrences and sectional architectures of the clayey breccias agree well with those of the paleo-weathering crust in these areas. Compared with the bedrocks, the paleo-weathering crust is characterized by the leaching out of CaO and CO2, and relative enrichment of SiO2, Al2 O3, Fe2O3, K2O, Na2O, MnO and P2O5. The clayey weathered residues in the paleo-weathering crust are characterized by marked enrichment of REEs, much higher contents of LREEs than those of HREEs, markedly positive Ce anomalies and negative Eu anomalies, and a noticeable increase in other element contents besides Mo, Sn and U from the clayey weathered residues.

对最近在藏北羌塘盆地菊花山、肖茶卡、石水河等地区新发现的肖茶卡组顶部的粘土质角砾岩的地质、地球化学特征研究表明：其岩石矿物成分、结构构造、角砾层产状及剖面演化序列等与古风化壳的形成及其特征较为一致；相对于基岩，古风化壳的主量元素表现为CaO、CO2的淋失和SiO2、Al2O3、Fe2O3、K2O、Na2O、MnO、P2O5等不同程度的相对富集；古风化壳中的粘土质风化残积层的稀土元素具有明显的富集，表现为LREE含量远大于HREE的特征，存在明显的Ce的正异常以及Eu的负异常；微量元素除Mo、Sn和U外，粘土质风化残积层的其余元素含量均有明显的增加。
