The absorption resistance has something to do with lithology,degree of lithogenesis and thickness of caprock.The smaller the grain size of caprock is, the higher the content of clay mineral is, the stronger the degree of lithogensis is and the thicker the caprock is, the stronger the absorption resistance and the sealing ability of caprock are.

盖层封闭游离相烃类的能力由两部分组成，一个是盖层底部岩石的排替压力，一个是盖层毛细管孔隙的吸附阻力，盖层毛管孔隙的吸附阻力与盖层岩性、成岩程度、厚度有关，盖层岩石的粒度越小、粘土矿物含量越高、成岩程度越强、厚度越大、盖层的吸附阻力越大，盖层的封闭能力越强。

Focusing on the PGE enrichment mechanism in the basic-ultrabasic intrusions in the Panxi rift, firstly, through the interpretation of TM photograph, data processing of regional geochemical exploration and geophysical prospecting results of gravity, magnetic force and seism, we analyzed the controlling effect of structure and magmatic movement on the PGE mineralization; Secondly, through the study of volcanic apparatus, petrography, measurement of comprehensive geochemical section, isotope tracing and dating of typical PGE-rich melanocratic rock series, we discussed the sources of the PGE-bearing mafic-ultramafic intrusions and basalts, their timing, evolvement sequences, the geochemical processes of magma crystallization and fractionation, and the relationship between magma evolution and structural development; Finally, through the analysis of PGE and chalcophile elements concentrations in the melanocratic rock series and the contrastive study with the Noril''sk magmatic Ni-Cu-PGE sulfide deposit, its related continental flood basalts and Siberia Traps, we discussed PGE mineralization characteristics and its enrichment mechanisms in the melanocratic rock series in the Panxi rift.
