Maninjau Lake is a caldera lake located in Agam, West Sumatra. This lake was formed from the volcanic activity of Mount Maninjau Purba about 60,000 years ago. The volcanic material resulting from the eruption is scattered and deposited in various pla

Volcanic ash is dispersed into the air when an eruption occurs, whilst the magma that reaches the surface of the Earth cools to form igneous rocks before eventually breaking down to form sedimentary rocks. One of the places where the sedimentation of

The elemental composition in peatland samples has been measured using the XRF (X-Ray Fluorescence) instrument. Peat soil samples were taken using a peat core near the Lake Diatas Alahan Panjang. After the magnetic suceptibilty of the samples were mea

Peatlands are formed from the accumulation of organic matter that originate from weathering vegetation for a long time. Minerals within peatlands can come from volcanic ash and consist of several types of minerals, one of which is magnetic minerals.

Peatlands in Lake Diatas can store various types of minerals. One of the mineral phases that can be found in peatlands are magnetic minerals derived from volcanic eruptions. This study was used to determine concentration of magnetic minerals found in

Lake Maninjau was formed after a caldera forming eruption ∼50,000 years ago. Eventhough this eruption is one of the biggest Quarternary eruptions on Sumatra, it is not studied in detail so far. Only few attempts to study the volcanic processes have

The rocks on the surface of the earth have different formation process, beginning with the lava of volcanic activity that flow on the surface of the earth and then cool down forming igneous rocks. Rocks derived by volcanic eruptions contain different

Determining the bathymetry of lakes is important to assess the potential and the vulnerability of this valuable resource. The dilution and circulation of nutrients or pollutants is largely dependant on the volume of water and the incoming and outgoin
