The objective of this study was to understand the mineralogical characteristics of the bentonite and its upper developed soil, at Nanggulan Kulonprogo. Separation and collection of clay fraction were done by fractionation on suspension at pH 10 after organic matter was oxidized using H2O2. Characteristics of clay mineral was analyzed using X-ray diffraction on parallel oriented samples after Mg saturation, glycerol solvation, or K saturation, and its following successive heating at 100°C, 300°C and 550°C. Cation exchange capacity (CEC) and the exchangeable bases were analyzed using saturation of NH4OAc 1N pH 7. Results showed that clay materials of both samples were Ca-bentonite. Comparing with clay from soil, bentonite had peak intensity of the semctite minerals and low value of CEC and exchangeable Ca. Potassium saturation caused incompletely shrinkage of the studied smectite minerals, and it was reflected by a broader peaks at 13,11 Å. The presence of these broader peaks was interpreted as a growth of interlayer materials that it may alter to smectite-chlorite intergrade minerals.

Open-pit coal mining as done by the coal mining site Melak have a impact on the surrounding natural environment. The impact of mining operations is that the land becomes unproductive and erosion is very high because of loosing its vegetation on ex-mining land. Vegetation influence the sensitivity of the soil to withstand destruction and transportation by rain and surface runoff and the occurrence of landslides. Analysis of soil erodibility factors seen from the physical-chemical properties of soil is one of the causes of erosion by using organic element parameters, soil structure, permeability, texture. The observation location was carried out on the disposal slope and low wall in-pit that has been revegetation with the hydroseeding technique. This research was carried out by making a design of erosion and sedimentation plots in the form of a zinc boundary measuring 2 x 2 m2, each box divides into three columns. The division of three columns in each box is done to get representative repetition data. Taking soil samples is carried out in each box using a sample ring.

Activities of Old Lawu volcano in the past resulted in various soil development in the south side of the volcano, especially in the area of the east side of Wonogiri and west side of Ponorogo, that located in the Java island. This area is also famous as herbal crops producer for raw materials of traditional herbal medicine industry. The purpose of this research is to identify the process of exposure of the parent materials in the Old Lawu volcanic environment, the development of the soil parent materials, and the mineralogy variation. Four Sites with different geological formation were observed, and each Site was selected for soil profile identification on the process of weathering of rocks. All layers of each profile were then sampled and then sand fraction of the fine earth particle was determined for the mineral type using X-ray diffraction (XRD). The results showed that materials of the Old Lawu volcanic activity that was of quaternary period had sized material of gravel, sand, silt, and clay. These materials were then exposed and undergone the process of weathering, transportation, and sedimentation according to the landform at that period. The development of soil as geoheritage in this region was influenced by the material size, landform, and settling process. There are four typologies of the environment on the soil development at the present study, there are: (1) Soil that developed in the inter-fluvial basins is characterized by thick soil and a clear horizon differentiation process as a feature of maturity stage of soil development. (2) Soil developed on the slope of hill area is characterized by shallow in solum and it is in early-stage soil development. (3) Soil developed on the volcanic materials that were transported and sedimented in the river environment is characterized by the thick soil above the layered fine size parent material with a variety of color. (4) Soil developed on the tertiary breccia showed early soil development.
