Alteration Analysis

The production of geothermal energy, which is among the renewable energy sources that are not harmful to the environment and the atmosphere, is of great importance in today's world where energy resources are gradually depleted. In this respect, our country has an important geothermal potential. Many geothermal resources are used in applications such as thermal tourism, residential heating and greenhouse cultivation.

Hydrothermal alteration zones are one of the important indicators for the exploration of areas. In the determination of hydrothermal alteration minerals, which are spread over very large areas, remote sensing methods are used with today's technological possibilities and large areas are evaluated holistically. In this way, great savings are achieved in terms of time and cost. In these studies, samples of hydrothermal alteration minerals are collected from the region, these samples are first evaluated in the mineralogy laboratory, the minerals are determined, and then the reflectance values ​​are obtained with a spectroradiometer device.

When the word alteration is mentioned, it is understood that the colored, chemical and mineralogical changes that the hot aqueous solutions create depending on the chemical and physical interactions with the host rock in the areas they pass through.

Types of alteration are due to surface or deep weathering. The alteration that occurs as the water originating from the surface descends into the depths of the soil is the surface alteration. Usually a few meters below the surface observed in the region. Surface weathering type aluminum, nickel and iron deposits are formed. Deep weathering or hypogene alteration is the weathering caused by the effect of hot solutions originating from the deep.

The width of the alteration zone shows that the solution movement is high in the environment, the fluid-host rock interaction affects large areas and the mineral deposit formed in that region will be that large.

In the formation of hydrothermal alteration, the hydrological model of the fluids that make up the geothermal system has an important place. Hydrothermal alteration is the element exchange between the minerals in the rocks in the shallow depths of the earth's crust, the water that is filtered from the precipitation and circulated between the cracks and pores of the heated rocks, and the water that gets warmer as it goes down. In these systems, the interaction between the liquid and the rock creates a secondary mineral set and their size changes depending on the effective physical and chemical conditions in the environment. Many hydrothermal minerals are observed in active geothermal systems.

Our organization also provides alteration analysis services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
