Embodiment Construction

[0030] The present invention is described in further detail below in conjunction with embodiment.

[0031] Such as figure 1 As shown, the present invention provides a method for identifying multi-flow rhyolite porphyry based on geological survey, which specifically includes the following steps:

[0032] Step (1): Regional geological survey and effective information extraction.

[0033] Carry out regional geological surveys with the main purpose of discovering, delineating or predicting subryoline porphyry bodies, or systematically collect geological, geophysical, chemical and remote sensing survey data in the work area. On the basis of systematic collation and research, all valid information related to the sub-ryoline porphyry body is extracted.

[0034] Effective information specifically includes but is not limited to remote sensing interpretation of ring structure data, dike and branch data, thermal metamorphism data related to rock mass, lithology change data, stratum occ...

Abstract

The invention belongs to the field of uranium ore geological exploration, and particularly discloses a geological survey-based multi-flow secondary flow speckle rock identification method, which comprises the following steps of: (1) carrying out regional geological survey and effective information extraction; (2) carrying out petrology and mineralogy research on the target rock mass; (3) surveying the occurrence of the target rock mass; (4) surveying the characteristics of the contact zone of the rock stratum system; and (5) comprehensively analyzing and identifying the secondary flow speckle rock mass. According to the method, accurate identification of the secondary flow speckle rock can be realized; the problem that in volcanic rock type uranium ore exploration, secondary flow speckle rocks closely related to uranium mineralization cannot be accurately recognized, and consequently the uranium mineralization potential is inaccurately evaluated is effectively solved.

Description

technical field [0001] The invention belongs to the field of geological exploration of uranium deposits, and in particular relates to a method for identifying multi-flow rhyolite porphyry based on geological investigation. Background technique [0002] Volcanic rock-type uranium deposits are an important type of uranium deposits in my country. Sub-volcanic rock subtypes are an important component of volcanic rock-type uranium deposits. For example, uranium deposits such as Hengjian, Zhangmajing, Daqiaowu, and Dingjiashan are all sub-volcanic rock subtypes. Both genetically and spatially are closely related to sub-rhyolite porphyry. Subryoline porphyry is an important ore-controlling factor or prospecting indicator. Discovering and identifying subryoline porphyry is an important content of this type of uranium exploration and an important basis for evaluating metallogenic prospects. [0003] However, since subryoline porphyry is not a widely developed rock type, it is not exp...
