Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] The present invention takes the structure-magma-thermal event as the leading idea, combines the principles of structural petrography and geochemical petrography, divides the stages of chlorite alteration phase formation, geological occurrence and its alteration phase state characteristics, and restores Permeability of rock fractures, based on the microscopic analysis results of chlorite electron probe, calculate the structure and formation temperature of chlorite, determine its species and formation mechanism, analyze the coupling relationship between rock fracture permeability and chloritization formation temperature, Restoring the heat that thermal fluid passes through unit area per unit time during the formation of chloritization can effectively indicate the formation mechanism of tectonic-magmatic-thermal events formed by burial compaction paleother...

Abstract

The invention relates to a method for recovering chloritization heat flux. The method comprises the following steps of (1) collecting chlorite samples; (2) analyzing polished thin sections; (3) calculating chloritization strength; (4) carrying out electronic probe analysis on chlorite; (5) calculating chloritization temperature; (6) calculating chloritization heat flow density; (7) recovering tectonic-magmatic-thermal events; and (8) obtaining a diagenesis and mineralization mechanism, thereby obtaining the diagenesis and mineralization mechanism according to thermal fluid activity superposition and the tectonic-magmatic-thermal events. Through use of the method provided by the invention, diagenesis and mineralization of post-magmatic hydrothermal fluid or basin fluid can be indicated while chloritization heat flux is obtained; and the evolutionary history of paleogeotemperature is obtained through parameter analysis in the method, so that a basic data support is provided for the diagenesis and mineralization mechanism and a structure-fluid coupling mechanism and the method can be widely applied to the technical field of geology and mineral resources.

Description

technical field [0001] The invention relates to the technical field of geological engineering, in particular to a method for recovering heat flux of chloritization. Background technique [0002] The formation process of chloritization is a water-rock reaction process controlled by geochemical reaction kinetics, which is affected by temperature, pressure, water-rock ratio, oxidation-reduction conditions, fluid composition, host rock chemical composition, petrophysical properties (such as fracture density, Permeability, porosity) and other factors are restricted. Therefore, the geochemical parameters of chlorite minerals can reveal the fluid activity and superposition history of the basin. Compared with geological thermometers such as vitrinite reflectance, mineral inclusion temperature measurement, apatite fission track, biomarker stereoisomerization, and diagenetic authigenic clay mineral thermometers, chlorite thermometers can not only restore paleothermal events and The ...
