【正文】 magmatic deposits surrounding rock does not have a significant alteration phenomenon. The ore and the wall rock basically have the same mineral position, when the useful minerals of the rock body aggregate and reach a certain size,they bee the orebody. The ore of magmatic deposits often have,disseminated,the banded,eye porphyritic,dense massive,brecciated and so on,ore ores structure can be broadly divided into the following categories: subthe different magmatic condensate crystalline or stacking interactions。 the structure of the immiscible fluid crystallization process the changes in the structure of the physical and chemical structure. The magmatic deposits forming temperature is high, generally between 1200 to 700 176。 C. The mineralization depth changes,generally formed in the ground a few kilometers to tens of kilometers. formation conditions of magmatic depositsMagma deposits are mainly derived from the magma, it is the bined effects of the product by a variety of geological factors, which playing a leading role is the geochemistry of oreforming elements traits, the magmatic rock conditions, tectonic conditions and physical and chemical conditions and so on. Control the conditions of magmatic rocks formed by magmatic depositsMagma is the main provider of the metallogenic material of the magmatic deposits and the medium of containing mineral ,how much of the content of useful ponents of magma is the possibility of the formation of magmatic deposits. rocks metallogenic specializationMetallogenic specialization of magmatic rocks in the genesis of magmatic rocks with endogenous deposits showed regular contact, and specific types of magmatic rocks are often produced specific types of deposits.a) With mafic and ultramafic intrusive rocks related depositsMafic and ultramafic rock is the plex igneous plex formed by the bination of a variety of rock types, rock types
