| dc.description.abstract | Gold is often found in very small amounts associated with other sulphides and oxide mineral hosted by various lithology and structural features. Gold is mostly found with quartz veins. Fractured quartz veins may be found as small rock float which is fragment in river beds or as large veins in cutting the geology of host rock. The white color of the quartz makes it easy to spot in many environments (Heng and Singh, 1986). Alluvium or placer is a deposit of eroded materials and sediment that is accumulated in low lying area. As gold and other materials are eroded, the small pieces are pushed by water and other forces into creek and river beds and other depressions. Because the density of gold is higher than most naturally minerals and rock, it settles at the bottom of these deposits. Intrusive rock as granite is formed when molten magma is pushed between layers of existing rock. Intrusive rock is typically very hard and erodes slowly. This allows the weathering process of surrounding rock to be happened, leaving only the harder rock in that place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away. Geochemical exploration is the survey with the aim to find any possible surface mineralization and to identify hidden ore deposits. The mineral exploration using geochemical survey to find ores must be conducted systematically because it consumes a very huge cost and time. It is generally integrated with geological and geophysical surveys. The grab sampling method can be done easily once the mineralization point is being identified. There also have other sampling method such as rock sampling, soils sampling, and stream sediment sampling which known as systematic geochemical survey. A systematic geochemical survey has been applied to CMNM Gold mining at Ulu Sokor, Tanah Merah Kelantan which covers an area of 2370 acres and it is accessible by travelling southwest from town of Tanah Merah. A total of 19 samples have been collected and analyzed by Atomic Absorption Spectrometry ( AAS ) comprising of one stream sediment, one soil, and 17 rocks. The area is underlain by mildly metamorphosed volcanoes of Permian and Triassic age. The Permian rocks are mostly found in eastern part of area which mostly dominant by phylite that also intercalated limestone, slate, metasandstone, and schist. As for the Triassic is mostly found in western part of area. | en_US |
