Problems solved by technology

However, for non-magmatic hydrothermal deposits that are obviously controlled by structures, such as reformed deposits and metamorphic hydrothermal deposits, there has not been a large-scale positioning and prediction of altered lithofacies prospecting methods for such deposits in depth.

Embodiment 1

[0039] Example 1: Prediction of ore prospecting in the deep location of a lead-zinc deposit in northeastern Yunnan

[0040] 1、 work background

[0041] A lead-zinc deposit in northeastern Yunnan is one of the main mines in my country's lead-zinc industrial base. However, due to decades of development, the mine's mineral resources are in a serious crisis or even exhausted. There are three major problems in prospecting in this area: it is located in an alpine and high-altitude area, with steep mountains and complex terrain; it is obviously more difficult to understand, and the metallogenic laws of ore deposits are unclear; it is very difficult to predict ore prospecting, and conventional methods are difficult to work. The prospecting of such deposits often adopts TEM and IP geophysical prospecting methods, but the inference and interpretation of resistivity and high polarizability anomalies obtained by these geophysical prospecting methods are highly ambiguous, and water-be...

Embodiment 2

[0061] Example 2: Prediction of ore prospecting in the deep location of a copper deposit in the Kangdian axis

[0062] 1. Geological background

[0063] The piercing structure is a typical and common special ore-controlling structure on the Kangdian axis, controlling a series of large and medium-sized copper deposits. Among them, this deposit is one of the large copper deposits strictly controlled by piercing structures. The mining area is located on the west side of the rift basin in the middle section of the Proterozoic Kunyang Rift between the Lvzhijiang Deep Fault and the Xiaojiang Fault. In the strongly silicified dolomite of the Lvzhijiang Formation of the Mesoproterozoic Kunyang Group through the structure and its surroundings.

[0064] After decades of development, the mine's mineral resources have been exhausted. Therefore, how to predict the location of hidden mines in the deep and peripheral mines is not only an important technical problem, but also a major tas...

Embodiment 3

[0084] Example 3: Prediction of ore prospecting in the deep location of a copper-lead-zinc deposit in Southwest Sichuan

[0085] 1. Brief geological background

[0086] A certain ore deposit is a large structural hydrothermal copper-lead-zinc deposit in southwestern Sichuan, which is obviously controlled by compressive torsional faults. Some sections can independently delineate industrial ore bodies. The hydrothermal alteration such as iron dolomitization, pyritization and calcite is strong and developed, and its characteristics are similar to those in Example 1, which provides favorable conditions for the application of the method of location prediction of altered lithofacies.

[0088] (1) Ore deposit metallogenic structure analysis and alteration mapping stage

[0089] Through the analysis of structures in different directions in the mining area, it was identified that the ore-form...

Abstract

The invention discloses a large-scale alteration lithofacies positioning predicating method for a hydrothermal deposit. Deep deposit or ore body direct positioning predicating is conducted through working procedures of an ore-forming structure elaborate analyzing and alteration lithofacies mapping stage, an alteration lithofacies zoning stage and a buried ore positioning predicating stage. According to the method, the problem that deep buried ore bodies are difficult to predicate due to strong abnormity multiplicity and difficult full spatial domain positioning of a conventional objectifying prospecting method is solved.

Description

technical field [0001] The invention relates to a method for location prediction of a large-scale concealed ore deposit, in particular to a method for location prediction of a large-scale altered lithofacies location of a hydrothermal ore deposit, and belongs to the field of mineral resource exploration. Background technique [0002] Prediction of deep ore prospecting is the scientific frontier of metallogenic and metallogenic prediction and one of the main problems in the field of ore deposit exploration, and it is also the main direction and trend of mineral exploration in the future. Traditional physical and chemical prospecting methods mainly use the differences in physical property parameters and element content of surrounding rocks and ores to indirectly infer whether there are hidden deposits or ore bodies in the deep. However, physical and chemical prospecting methods are indirect prospecting methods, often due to The results of deep ore prospecting predictions are o...
