| Popis: |
The specific magnetic properties of bottom sediment from different geological areas were studied. Magnetic susceptibility has been used for observing movement, distribution and accumulation of magnetic minerals in the bottom sediment from rivers and catchment area. SIRM, S-ratio and k are used to identify the sources and classify the magnetic minerals which are formed in the bottom sediment of abandoned tin mines. Magnetic susceptibility from two rivers increases from river source to catchment area, and from the catchment area to the end of bay. The bottom sediment from abandoned tin mines contains the mixture of ferrimagnetic material and more antiferomagnetic material. The magnetic minerals in the abandoned tin mines, U-Tapao river and Bangyai river are found in geochemical materials such as soil and rock found around the area. |
