The Dongying Basin, Huimin Basin, and Zhanhua Basin constitute the jiyang Depression in Shandong Province. They are major oil and gas exploring districts within the depression. Through reconstructions of the paleotemperature of the three basins facilitated with the chlorite geothermometry, the thermal history of the Paleogene prototype basin in jiyang Depression and its geologic significance were explored. This study reveals that the Si^(4+) component in chlorites reduces gradually as its buried depth increases, while the AI~Ⅳ component increases accordingly. The chlorite type changes from silicon-rich diabantite to silicon-poor ferroamesite and prochlorite. The prochlorite in this district only appears in the deep buried depth, high temperature, and relatively old stratigraphies; while the diabantite appears in the shallower buried, low temperature, and newly formed strata; the ferroamesite exists in the conditions between prochlorite and diabantite formation. The diagenetic temperatures of the chlorites in these Paleogene basins are 171 — 23.℃ for the Dongying Basin, 160—202℃ for the Huimin Basin, and 13.—180℃ for the Zhanhua Basin. The differences of the chlorite diagenetic temperatures in the three basins were controlled by the duration time of the structural depressing processes. Higher temperature indicates longer depression time. The relationship between the chlorite diagenetic temperature and its buried depth indicates that the average paleogeothermal gradient is about 3..3. /km in the Paleogene prototype basin of jiyang Depression. It was higher than the present geothermal gradient (29—3.℃/km). This phenomenon was attributed to the evolution of the structural dynamics in the depression basin.

山东昌潍盆地形成于古近系的古新世-始新世早期(Ek-Es_4),本文主要研究昌潍盆地的粘土矿物特征及其古地温。昌雄古近系(Ek-Es_4)原型盆地的粘土矿物种类有:无序高岭石、伊/蒙混层矿物、伊利石和辉绿泥石(铁斜绿泥石)。利用粘土矿物温度计估算了盆地埋藏深度的古地温,探讨了古近系(Ek-Es_4)原型盆地的成岩作用和有机质热演化阶段。研究表明:随着埋藏深度的增加,伊/蒙混层矿物(L/S)由无序向有序连续转变;高岭石的有序性、伊利石和绿泥石的结晶程度趋于增强。根据伊/蒙混层矿物(L/S)地温计获得盆地不同深度的成岩温度范围;成油深度约为3.00～4000m±。现今地温与古地温的对比,显示盆地存在热异常,导致热异常的形成可能有以下几方面因素:(1)盆地曾经历过地壳抬升阶段;(2)盆地内有岩浆活动热事件发生;(3.盆地裂陷期的构造动力学作用导致古地温梯度过高。昌潍原型盆地较高的古地温梯度吻合于裂陷盆地构造动力学演化的模式。
