There is gravity measurement that is supported by magnetic measurement in Sangon to identify porphyry body and geological structure as low sulfidation epithermal system control. The survey area is 6.4 x 5.6 km for gravity method and 2.5 x 1.2 km for the magnetic method. The value of gravity anomaly after flat plane reduction processing is 122-142 mGal which is positive anomaly located in the north-eastern area and negative anomaly to 82- 102 mGal located in the south-western area. Whereas the magnetic residual anomaly is - 800-1300nT.Conducted 2.5 D modelling of gravity method that is based on local anomaly slice. The result of 2.5D modelling show that an intrusion body interpreted as Dacite intrusion as host rock which plays a role as a heat source of the mineralization system. The density of Dacite is 2.70 gr/cm3. The result of gravity modelling has a correlation with the result of magnetic modelling. Based on magnetic modelling, the intrusion body is located in the south-west.

Ice and Bell Sounds are two large fiords opening out on the west coast of Spitzbergen, which cut deep into the country, both in an easterly direction towards Stor Fiord, and in a northerly direction towards the south part of Wijde Bay. The shores of the Sounds are for the most part occupied by high mountains, precipitous towards the sea, nearly free from snow during the summer, whose sides, being bare of vegetation, offer the observer an uncommonly favourable opportunity for studying the geological structure of the rocks. Within an excecdingly limited space one meets here with a succession of strata belonging to a great many different geological periods, and rich in fossils, both of the vegetable and animal kingdom.

Hydrometeorological Conditions

<p>The contemporary morphogenetic system of the South Baltic Sea is clearly changing, both in the annual and long-term weather cycle. Morphogenetic seasons are subject to change, both in terms of duration and types of morphogenetic processes and related forms of relief. The duration of the late-autumn and early-spring season is clearly increasing, which is associated with the occurring climate change and related hydrometeorological conditions. All this means that the morphodynamic types of the South Baltic coast are subject to change, the nature of which is conditioned by geological structure, relief, land cover and, hydrometeorological conditions. Undoubted individuality of the geo-diversity of the South Baltic coast in Poland are postglacial cliff coasts (50 km long).</p><p>Systematic geomorphological mapping of cliff coasts carried out since 1975 which have recently been supported by GIS methods, allow the recognition of cliff coast development mechanisms, emerging landforms and associated morphodynamic types of the South Baltic coast.</p><p>Based on repetitive geomorphological mappings, the following morphodynamic types of the South Baltic cliffs can be distinguished: landslide-type, rock fall-type, talus-type, slump-type and flow-type.</p><p>The basis for the typology of morphodynamic types of cliff coasts was the dominant types of relief forms, including lithology, exposure, land cover and hydrometeorological conditions. It can be unequivocally assumed that the morphodynamic types of the cliff coast is a good indicator feature of monitored morphogenetic systems and their space-time variability.</p><p>The effect of the observed climate change is the increasing frequency of storm surges that initiate denudation processes of an extreme nature. Another consequence of the observed climate changes is the increasing variability of morphodynamic types of the South Baltic cliff coast in the analyzed morphogenetic seasons with a greater share of landslide and rock fall-types.</p>

The alpine nappe sequence of the wider area of Aegialia and Kalavryta (Aegion sheet) is comprised of 3 alpine units, which from the lower to the upper are: (i) Arna unit, which consists of phyllites and quartzite series, (ii) Tripolis unit that consists of Tyros beds, neritic carbonate sequence and flysch and (iii) Pindos, unit which is represented with all its formations from the Triassic clastic formation at the bottom up to the Eocene flysch at the top. Pindos unit is intensively folded and tectonized forming successive thrusts with direction from east to west. The post alpine deposits are distinguished to (i) fluvial, (ii) fluvial-lacustrine, (iii) lacustrine, (iv) fan delta and (v) marine formations. The lacustrine and the fluvial formations outcrop at the south, central and eastern part of the study area, whereas the fluvial-lacustrine formations, the fan delta deposits and the marine deposits outcrop at the northern part. In the study area normal listric and oblique slip faults of great length have been observed striking WNW-ESE and NW-SE. Also, normal, oblique-slip and strike-slip faults have been observed striking NE-SWto N-S, which were which are younger than the former ones (WNWESE). The tectonic structure of the study area is characterized by the presence of horsts, grabens and blocks, which have been tilted towards SE, and S.

<pre>Coal exposure founded at Klatak Kebo Ireng village in Besuki Tulungagung precisely in the vicinity of the river. Energy needs is increasing so the coal used for one of alternative energy source that can be used by society. This study was conducted to determine of the potential distribution coal modeling on geological structure. Identification of coal structure is using Ground Penetrating Radar (GPR) 2005 it conducted because this method is more suitable for shallow of surveys. The location for taking data is around the river that showed to exposure. There are 5</pre><sup>th</sup> lines of taken data with length about 50 until 100 meters. Data processing was done using of software Future series 2005. The data displayed with software in the color pattern to obtain based on the constant of dielectric and conductivity. The results of interpretation study are the data indicates that there is a coal on the overall trajectory. Only in 2<sup>nd</sup> track contain little of coal. The Coal layers are appear in processing the results of data is thickness about 6 at the top. In the area of study also found the cavity (cavity area) which contained of several tracks. On the bottom of the track there is a pattern of coal reddish of yellow color which indicates that material contains of minerals.
