Hamster this-http://www.uta.edu/geology/de_lab/labmanual/chap6.html The August program was successful in three respects. It validated the structural targeting method as an efficient way to locate mineralization, it re-affirmed the diamond potential of the area by the collection of many samples with large amounts of magmatic mineral crystals and it generated a new discovery consisting of the first encounter with gold mineralization in the volcaniclastic rocks of the Chinchaga area. Soil and rock auger samples collected on a large elliptical structure adjacent to a major expansion fault were submitted for standard fire assay and returned distinctly elevated gold values. Numerous samples exceeding 0.1 g/tonne were obtained with the highest value reaching 1.4 g/tonne. The gold mineralization discovered in the August program appears to be related to volcaniclastic rocks located adjacent to a 400-metre wide expansion fault. Marum Resources, the project operator, found the results to be so geochemically significant that the September program was modified to explore for the possible existence of gold over a much larger area, along the same faults as well as along parallel faults that traverse the area.The September exploration program was carried out using two crews; a three-person helicopter-supported crew manned by our consultant Apex Geoscience and a truck-supported crew consisting of Marum Resources employees. The Marum crew was equipped with a trailer mounted sampling drill that can collect large samples to a depth of about 20 metres in the soft Chinchaga bedrock. Both crews were mandated to search for volcanic or volcaniclastic outcrops along fault systems, to seek out sulphide-rich zones and to take additional samples for gold. Both crews succeeded in all respects and collected numerous samples that have just arrived from the field. The only analytical results available from the September program at this time are fire assay results for six rock samples taken from outcrops extending over a distance of 33km. The results, although limited and preliminary, suggest the presence of regional gold mineralization within a continuous stratigraphic unit of as yet unknown thickness. Using the standard fire assay method at Loring Laboratories in Calgary the gold values obtained were 0.035 g/tonne, 0.250 g/tonne, 0.325 g/tonne, 0.640 g/tonne, 0.750 g/tonne and 46.67 g/tonne. The host rock appears to be a medium-grained volcaniclastic rock with moderate visible sulphide mineralization. Stratigraphically, the gold mineralized rock unit lies immediately below a base metal- and nickel-rich volcaniclastic unit that was intercepted in drill core last winter. From the ABOVE URL: METAMORPHIC : 2. Regional metamorphism Regional metamorphism is a general term for metamorphic events affecting an large geographic region. This form of metamorphism is caused by the directed pressures, pressures related to depth (commonly 3,000 to 10,000 times that of surface pressure), temperature (between 400 C and 800 C), and shearing stresses related to the compressive forces of lithospheric plate movements. These conditions can only be found in large orogenic belts, thus the metamorphism is always regional in character. The mechanical deformation of rock is extensive. Chemically active fluids are of secondary importance. -------------------------------------------------------------------------------- METAMORPHIC MINERALS -------------------------------------------------------------------------------- As noted in the Introduction, new minerals are formed from rocks during the process of metamorphism. Many of these minerals are the same as those which comprise igneous rocks, such as: quartz, feldspar, amphibole, pyroxene, biotite, and muscovite. In addition, new minerals are formed which are found almost exclusively in metamorphic rocks. Regional metamorphic rocks exhibit the metamorphic minerals, chlorite, epidote, garnet, staurolite, andalusite, sillimanite, and kyanite. These minerals are listed in Table 6-1 and you should review their properties. Remembering that most of the materials of the earth are made up of only 8 elements and that silicon (Si) and oxygen (O) are the most abundant elements found in crustal rocks, you should not be surprised to learn that all of these uniquely metamorphic minerals are also silicates made up of silica tetrahedra bound together by one or more of the elements: aluminum (Al), iron (Fe), calcium (Ca), sodium (Na), potassium (K), and magnesium (Mg). All metamorphic minerals except chlorite and epidote occur commonly as large crystals surrounded by a finer grained groundmass. They look somewhat like the phenocrysts in porphyritic igneous rocks but have a very different origin. New minerals are also formed by contact metamorphism in rocks surrounding igneous intrusions. If the surrounding (country) rock is a carbonate (limestone or dolomite) and contains some clay or quartz sand, the metamorphic minerals wollastonite (a calcium silicate) or diopside (a calcium and magnesium silicate) as well as andalusite and garnet may form by recrystallization. The heat generated by the high temperature of the intrusion is sufficient to cause this level of metamorphism. If hot fluids produced near the intrusion penetrate and chemically react with the country rock, many new minerals may form including economically important deposits of lead, zinc, tin and other ore minerals.
