Various data demonstrate that ore-forming material of the Shaxi porphyry copper (gold) deposits came mainly from magmatic hydrothermal solution. characteristics of the mineralized porphyry ought to include all the features related to mineralization of the stock, especially features of postmagmatic hydrothermal activities. Based upon the shape, mode of occurrence and emplacement form of the stock, physicochemical behaviors of the magmatic system, and properties of postmagmatic hydrothemal activities, the authors have deduced the prerequisite for the formation of the mineralized porphyry: the condition of the magmatic-hydrothermal system is extremely distant from the equilibrium state, sufficient ore-forming materials are supplied due to the favorable physicochemical properties of the magmatic-hydrothermal system; the hydrothermal system related to porphyry is half-closed, that is, on the one hand, it constantly exchanges materials and energy with surrounding media such as magma, wall r(?)cks and ground water, and, on the other hand, the ore -forming materials should be relatively concentrated without dispersion.

各种数据资料证明沙溪斑岩铜(金)矿床成矿物质主要来自岩浆热液。矿化斑岩体的特征应包括与矿化有一定内在联系的岩体的各种特点,特别是岩浆期后热液活动的特点。根据岩体的形态、产状和形成方式,岩浆体系的物理化学性质,以及岩浆期后热液活动的特征,推断矿化斑岩体形成的充分且必要条件是:岩浆一热液体系极端远离平衡态;岩浆-热液体系的物理化学性质使其能够提供足够的成矿物质;岩浆热液体系具有半封闭性,一方面不断与环境(岩浆源、围岩、地下水)进行物质与能量交换,另一方面成矿物质又要相对集中不被逸散。

Crust_mantle metallogeny is an important bridge linking deep geology with regional metallogeny. The research of crust_mantle metallogeny through connecting the mineralization with the deep process has become an important trend of regional metallogeny. The key research content of crust_mantle metallogeny seems to be the relationship between continental multilevel crust_mantle interaction and mineralization, and the main technological support for the research of crust_mantle metallogeny is the “petroprobe” analysis. The crust_mantle metallogenic study on the xenoliths as well as their hosts and relevant deposits in several selected typical districts can be carried out through combining the analysis of evolutionary history with the discrimination of action process. This would give a clue to discriminating episodes of crust_mantle interaction and metallogeny as well as their temporal and spatial coupling relation and gain new insights into evolutionary history of multi_level magmatic_hydrothermal systems and their constraint on the enrichment of metallogenic elements for forming ore deposits. On the basis of this study, a model for regional crust_mantle interaction and metallogenic process is advanced, which can provide new thought and scientific evidence for establishing a new generation of metallogenic knowledge system.

As an important trace\|element micro\|analysis technique, scanning nuclear microprobe is applied broadly in many fields, such as geosciences and environmental sciences, life sciences, microelectronics, materials and metallurgical sciences, arts and archaeology, and so on. In this paper, the recent developments on microprobe facilities, analytical techniques and its applications in geosciences are reviewed. The last decade saw a great progress on microprobe facilities and analytical techniques. Especially external microbeam\|PIXE system, high energy heavy ion microprobe(single cell irradiation system) were developed in many laboratories. Besides, portable PIXE, Grazing\|Exit PIXE and multi\|function sample chamber were developed. As to its geological applications, there was a wide extension both in scope and depth. The studies of extra\|terrestrial samples provided new knowledge about the early history of the solar system and primary geological processes. The micro\|distribution of trace elements among coexisting minerals and fluid inclusions gave valuable information for the studies of a range of geological environments and ore forming processes in magmatic\|hydrothermal system. The distribution of trace elements and precious metals in ore samples presented basic data for mining and metallurgy. In addition, the major performances of various micro\|analysis techniques, such as SEM, EMP, TEM, AEM, SR\|XRF, LA\|ICP\|MS and SIMS are compared. Finally, the future developments and potential applications in geosciences of scanning nuclear microprobe are discussed.
