Abstract

The invention discloses a paleo-thermal lithosphere thickness determination method and device. The method comprises the following steps: obtaining rock heat conductivity and rock heat production rate of each structure layer in a research area; establishing a paleostructure layer model of the research area in a preset geological time by utilizing a stratum backstripping technology, and determining the thickness of each structure layer according to the paleostructure layer model; obtaining paleo-surface heat flow value of each structure layer in a simulated manner according to vitrinite reflectance actually-measured value; calculating top boundary heat flow values of each structure layer according to the paleo-surface heat flow values, rock heat production rate and the thickness of each structure layer; determining shallow earth one-dimensional heat conduction geotherm according to the top boundary heat flow values, the thickness of each structure layer, the rock heat conductivity and rock heat production rate; and determining the depth of the shallow earth one-dimensional heat conduction geotherm intersecting with a mantle adiabatic line as the thickness of the paleo-thermal lithosphere. According to the method and device, the paleo-surface heat flow and paleo-surface thickness can be obtained, and furthermore, the thickness of the paleo-thermal lithosphere is calculated; and the problem that the paleo-thermal lithosphere thickness and evolution cannot be determined in the prior art is solved.

Description

technical field [0001] The invention relates to the technical fields of geothermal science and geophysics, in particular to a method and device for determining the thickness of the paleothermal lithosphere. Background technique [0002] From shallow to deep, the earth can be divided into three parts: crust, mantle and core. The lithosphere refers to the hard lithosphere layer in the shallow part of the earth compared with the asthenosphere, which is a high seismic wave velocity zone. The lithosphere mainly includes the entire crust and the top of the upper mantle, composed of granitic rocks, basaltic rocks and ultrabasic rocks. In the professional field of geology, according to different physical and chemical properties or parameters, people endow the lithosphere with different titles and meanings, such as seismological lithosphere, chemical lithosphere, thermal lithosphere, etc. [0003] The thermal lithosphere involved in the present invention refers to the lithosphere l...
