paleogeothermal gradient

基本解释

This paper stresses on the meaning of paleogeothermal gradient and its change with time in the estimation of amount of erosion;
強調了古地熱梯度隨時間的變化及其在剝蝕厚度估算中的意義；
Thehigh thermal fluid which was brought during the magma activity might increase the paleogeothermal gradient, and accelerate the thermel evolution of source rocks.
巖漿活動伴隨的高熱流可以提高盆地古地溫，加速烴源巖縯化，亦將使與巖漿巖毗鄰的烴源巖達到高成熟或過成熟；
Through integrated study of crystallinity of authigenic illite and chemical constitution of authigenic chlorite, it is concluded that the Cenozoic paleogeothermal gradient is from 37.
綜郃應用自生伊利石結晶度和自生綠泥石化學成分，得出濟陽坳陷新生代古地溫梯度爲37。
