Abstract

Solok Selatan is already known as an area that has potential precious metal, Gold. Local mining scale can be found on site certain areas in Abai Region, especially in the North, which was previously believed to exist the presence of these minerals. Based on the consideration of associated mineral associations gold, of course the presence of other precious metals deserves further investigation such as Copper (Cu), Silver (Ag), Lead (Pb), Zinc (Zn) and Titanium (Ti). Exploration activities and geochemical analysis need to be carried out to determine the characteristics of the associated metallic minerals of Gold in Abai Region. A series of explorations carried out with a direct mapping mechanism to determine the topography, morphology, local geology, distribution of lithology and type of gold deposit. The collected samples will be tested in a chemical laboratory to determine gold content, chemical composition, and other metallic minerals. This research is expected to be able to answer the characteristics of the material (mineral) based on the geochemistry of precious metal compounds and can recommend better management in the presence of other precious metals.

Abstract

Mapping (exploration) and distribution of groundwater can be described vertically – horizontally. The distribution of rock formations storing/carrying water (permeable) is called an aquifer. Aquifers are strongly influenced by the degree of porosity and permeability of the rock. To obtain an aquifer, a study of geophysical studies needs to be carried out, namely the estimation of geoelectric resistivity, estimation to study the physical properties of rocks against electric currents. The implementation of the research was using three stages of the method; the first stage evaluates geological maps, hydrological maps, groundwater basin maps, topographical maps, and identifies groundwater conditions; the second stage is to explore and map resources, collect physical and chemical properties of water, and evaluate the condition of regional infrastructure at Balai Gurah; the third stage is evaluation and interpretation of exploration results, presenting a map of potential water resources, and evaluating water availability. Based on the CAT map, the flow capacity in the study area can reach 5 L/s, while in springs it can reach 100 L/s. In addition, the layer of shallow wells can reach 7-15 m and deep wells can reach 50m. Groundwater in the Balai Gurah area is greatly affected by changes in the wet and dry seasons. The results of shallow well measurements show that the position of the water varies with a depth of 1-15 m and a body thickness of 20 cm to 2 meters. The results of resistivity measurements indicated that there is a subsurface layer at a depth of 5m and also found the potential for deep groundwater at depths of up to 10m.Keywords: Groundwater, Aquifer, Geo-electricity, Hydrogeology, Agriculture, Water resources
