The temperature-pressure evolution path of mineralization process indicates that large deposits have relative complete P-T evolution path or fluid boiling, but relatively little deposits have not complete P-T path.
Fenshuiling Tremolite Mine is a large deposit,the tremolite ores can be used in sanitary ceramics,wall and floor brick adobe,glazed tile adobe and low temperature raw glaze. Contrasted to using ordinary raw materials,the products from tremolite have the better performance and the process can be under the lower sintering temperature.
The paper introduces the geological and metallogenic background of Halega Cu-Fe deposit and characteristics of ore bodies, mineralogy and distribution pattern of micro-elements and points out that the deposit is potential to become a large deposit according to the metallogenic conditions.
2. the mantle distances of all known 57 large scale deposits are less than or equal to 20 km, among these deposits, 94.7% deposits have mantle distances of less than or equal to 16 km, and mantle angles of less than or equal to 1°;
4. the spatial distribution relation between the large scale deposits and super large scale deposits has a common law of the so-called “Gold Law" of 0.618. It is concluded based on the mantle depression theory that there are over 450 large scale deposits and 79 super large scale deposits targets for the follow-up prospecting.
Acidic soil, large deposits of sulfur pollutants in relation to the critical load, the presence of soot and soluble salt, and conditions giving access to water and air were found to accelerate the deterioration.
The leading role of long-lived deep faults in the control of large deposits is emphasized.
The emplacement of large deposits has been controlled by the crossing of many different geological factors.
Obviously the enrichment of the regional mantle played an important role in formation of the large and super-large deposits in southern Hunan Province.
The geographical distribution of lead isotope ratios shows a zonation in Vazante Paracatu region, an area containing large deposits of zinc.
This is a large deposit containing more than 1000 t industrial reserves of gold and more than 0.5 mln.
The gold field contains one large deposit (Mina III, 65?tons Au) and several smaller occurrences, which are structurally controlled by regional shear zones that are either thrust or strike-slip faults.
Both sacs contain a single, large deposit of intracellular lipid enclosed by a very thin rim of cytoplasm and resemble mammalian white adipocytes.
The experiment was conducted at two adjacent sites that were physically similar but biologically different, one dominated by large deposit feeders and the other by large suspension feeders.
The results show that a large deposit exists in the direction NE-SW in connection with the radioactive cloud passing.
