University of Yangon, 2012 ABSTRACT __ The study area is located in Kyaukme Township, Shan State (North), covering about 28 square kilometer. It also lies at the east of the Shan Scarp. Stratigraphically, rock units mainly exposed of Plateau Limestone (Carboniferous), Nyaungbaw Formation (Siluarian), Namhsim Sandstone (Siurian), Pangyun Formation (Cambrain) and Chaungmagyi Group (Precambrian). The Chaungmagyi Group (Precambrian) consists of greywacke, phyllite and slate.
Plateau Limestone exposed in the southern and eastern parts of the study area. Nyaungbaw Formation is to be found only at the eastern flank of the metasedimentary unit. It consists mostly of thin to fhick bedded phacoidal limestone. And also, Namshim sandstone consists of fine to medium grained, bluewish brown color on the fresh surface and yellowish to brown color underlying by plateau limestone.
In the study area, there is north-south trending fault system which is only one prominent lineament system. In geochemical analysis, Cu, Pb, As, Zn, Au was determined by Atomic Absorption Spectrometer (AAS) method, the precious metal association of gold and silver elements has the lowest values in these veins. The base metal group of copper, lead and arsenic is moderate concentration in the veins. Zinc is also common element of the study area. Mean value and total range for gold is closely associated with silver element.
Gold Mineralization occurs in Namshim Sandstone such as sedimentary hosted at North-West of Pangmalawt village. The GPS location of the study area is N 22° 25.602 E 096° 48.564, elevation is 727m near the Maintan Chaung. There is only one new adit in the study area, the direction of adit is 30° and the length of this adit is 6m.
There are two types of alternations, especially sericitization and silicification.Sericitization is a prominent alternation in the mineralized zone. It is often associated with a few intensity of silicification. The ore controls can be considered as structural controls, lithologic and stratigraphic controls and source of magmatism is not significant. The mineralization of the study area is generally considered to be probably epithermal sedimentary deposit in the upper zone. The possible age of gold mineralization in Pangmalawt area is post Paleozoic Era. M.Sc.
