The section between Tal to Talekhu of Manang District lacks the detailed geological study. The geological mapping in the scale of 1:50,000 followed by the preparation of geological cross-section and lithostratigraphic column has been done in the present study. The studied area lies partially in the Higher Himalayan Crystalline and the Tibetan Tethys Sequence. The units of the Higher Himalayan Group from Tal to Talekhu consists mainly of vigorous to faintly calcareous gneiss, migmatitic gneiss, quartzite, granite, etc. They are named as the Calc. Silicate Gneiss and Paragneiss and the Orthogneiss and Granite units. The lowermost part of the Tibetan Tethys consisted of metamorphosed calcareous rocks containing silicates and feldspar, so this unit is termed as the Marble and Calc. Gneiss. The section is about 9 km in thickness and is highly deformed with presence of igneous rocks at many places.

In 1895, self-trained mining engineer William K. Gordon, Sr (1862-1949) conducted a geological reconnaissance trip to far West Texas in search of coal deposits. A report from that trip reveals how Gordon's training in geology (acquired largely through reading) and his intrinsic interest in stratigraphy and geomorphology helped him effectively advise the Texas and Pacific Coal Company about the bleak prospects there. In 2005, using Gordon's never-before consulted field report, the author retraced, or rather re-hiked, Gordon's route. Gordon's report features hand-drawn maps and a geological cross-section that were field checked and compared to later data. The author concludes that Gordon enthusiastically, but often inaccurately, described the complex petrology in the rugged, semi-arid Eagle Mountains. Gordon was evidently vexed by how to identify some of the highly varied extrusive igneous rocks here. Nevertheless, Gordon's work should be recognized as the earliest serious geological reconnaissance in a remote area that would much later (1963) be studied in detail by geologists who had at their disposal considerably better tools to analyze the petrology, and possessed a growing awareness of plate tectonics that were unknown in Gordon's time.

Amber of amber-bearing deposits in Rivne-Volyn region of Ukraine has been analyzed. Relying upon instrumental techniques, physical and chemical as well as spectral analyses, and geological prospecting of the deposits, chemical composition and ultimate composition of amber occurring at the territory of Klesiv deposit (Ukraine, Rivne Region, Sarny District) have been identified. Klesiv amber contains the greatest part of inclusions; it contains 18 chemical elements. Basing upon the performed geological cross-section it has been determined that the amber occur in sandy soil and sandy-shale soil. The depth is insignificant – from 1 m to 10 – 15 m. Moreover, to determine the cost, experimental technique has been developed. The technique involves classification of the amber fragments according to their form, dimensions, and colour. Lithologic-and-facies sections of sites of Klesiv deposit have been obtained.

The Given

The results of the works undertaken by students on practical classes and during educational practices have been discussed. Causes and  difficulties in student learning of exploratory geophysics have been  analyzed. It has been found a deficiency in practical skills of future  engineers relevant to the work with geophysical facilities and  equipment and further mental processing of the measured  parameters of natural and artificial geophysical fields. A brief  description has been given for improvements in the methodology of  teaching geophysics to future geology and geoecology engineers via  inclusion of practical works with geophysical equipment on the test  site on the Zorge Street with tasks linked to engineering-geological  cross-section study and mapping underground infrastructure on the  given area. There are some other examples of student involvement  in solution of geophysical tasks on the objects of educational geophysical practices with subsequent detailed geological and  geophysical interpretation.

Complex Architecture

Glaciodynamic sequence stratigraphy provides a practical model for grouping and classifying complex geological data to aid interpretation of past climatic and environmental development in Quaternary successions. The principles of glaciodynamic sequence stratigraphy are applied here to summarise the complex glacial geological framework of Hvideklint on the island of Møn, south-east Denmark. The framework of the superimposed deformed Hvideklint is presented in a reconstructed geological cross-section of Hvideklint. For the construction of the architecture of the glaciotectonic complex, the interpretation of structures below sea level was based on a detailed new survey of the cliff section combined with construction of successive approximation balanced cross-sections. The new description is supported by drill hole data from the Jupiter database. Where chalk is not glaciotectonically deformed, the constructed depth to the top-chalk-surface is generally located about 30 m below sea level. In Hvideklint, thrust sheets with chalk are exposed 20 m above sea level, and the balanced cross-section constructions indicate that the décollement surface for a Hvideklint glaciotectonic complex is located about 80 m below sea level. Between the décollement level and the top of the complex, two or more thrust-fault flat-levels and connecting ramps add to the complex architecture of Hvideklint.
