Abstract

North Sulawesi has considerable geothermal potential as evidenced by the emergence of several types of geothermal manifestations, one of which is located in Kanonang village, precisely on the hill of Kasih Kanonang. The purpose of this research is to determine the rock structure and type of rock contained in the rock in the manifestation area located on the hill of love kanonang. The method to be used in this research is to analyze in the laboratory using SEM-EDX tools and FTIR tools. The results showed that the mineral content and mineral types of geothermal manifestations of hot springs in kanonang love hill have 3 elements namely Oxygen, Silica, and Aluminum with a percentage content of O 66.60%, Si 31.25%, and Al 0.73%.

Abstract

A literature review of the magnetic mineral properties of river sediments using magnetic susceptibility parameters was conducted to assess their potential for pollution monitoring. This study analyzed 28 articles published in journals/proceedings related to the topic of magnetic susceptibility of river sediments. Based on the results of the literature review, the magnetic susceptibility values ​​of river sediments show a high range. This means that with such (high) susceptibility values, river sediments are ferrimagnetic. Information obtained from magnetic susceptibility data of river sediments indicates a high Fe content. We also describe that there are frequency-dependent magnetic susceptibility (χFD) values ​​of more than 2 % in river sediments containing superparamagnetic grains (fine grains). River sediments with high susceptibility values and high Fe content can indicate that the river has been polluted.
