Relevance. The study area is located at Mandisha village, El-Bahariya Oasis, Western Desert, Egypt. It is suffering from lack of surface water. So it’s important to search for another source of water (as groundwater) that important for everything for live. Based on the literature studies; the main aquifer in the study area is located in the Nubian sandstone aquifer, which located directly on the upper surface of the basement rocks. So the depth of the lower surface of the Nubian sandstone aquifer is equal to the depth of the upper surface of the basement rocks in the study area.
Objectives of the study. This study is used the analysis and interpretation of magnetic data to determine the depth of the basement rocks and the structural elements that affected on the basement rocks at Mandisha area in El-Bahariya Oasis, Western Desert, Egypt.
Research methodology. The Magnetic methods were applied to achieve these goals. One hundred and seventy four magnetic stations were acquired by Overhauser magnetometer instrument (GSM-19 “V7.0”). The magnetic data were processed by using Geosoft Oasis Montaj program. 2D Magnetic Profiles and 3D Magnetic Modeling were established to construct basement relief map in the study area. First Vertical Derivative Technique, Source Edge Detection Method and 3D Euler Deconvolution method were established to determine the locations and directions of faults that affected on the Basement Rocks in the study area.
Work results. The most important results of this study: 1. The depth of the basement rocks in the study area ranges from 1200 m to 2000 m. 2. The northeastern, northwestern and western parts of the study area are characterized by shallow depth of the basement rocks, while the southern and eastern parts of the study area are characterized by deep depth of the basement rocks. 3. Deep faults (more than 2000 m) were located at northern part of the study area. 4. The main direction faults in the study area are NE–SW and E-W direction.

Relevance of research. The study of the origin of oil is fundamental in geology, with essential scientific and practical importance. In connection with the gradual exhaustion of deposits of small and medium depths (up to 4.5 km), the question inevitably arises of the development of deeper hydrocarbon
The purpose of the work: to estimate the depth to which it is currently possible to detect oil fields.
Methodology of the research: analysis of theoretical models of inorganic formation of oil and the deep structure of the earth’s crust with the involvement of new data from experiments and global discoveries of deposits at super depths.
Results. Based on the rheological model by S. N. Ivanov (about the structure of the continental crust), the deepest oil fields should be located immediately below the separator, that is, directly under the fluid-tight boundary, usually at a depth of 10–11 km. According to the model of oil formation by A. I. Malyshev (model of cooling horizons), the maximum depth for oil fields is 12 km. Oil deposits with a depth of 10.7 km are already known. Tests by V. S. Balitsky and others on the phase states of water-hydrocarbon fluids at high temperatures and pressures show that there may be oil deposits of at least 12 km. Now, the same depth is maximally achievable when drilling.
Conclusion. Finding oil fields is possible to a depth of 12 km. However, the concept of the inorganic oil origin does not assume the necessity and expediency of searching for its deposits in the basement of Western Siberia and Yamal, over vast areas outside the known oil-bearing regions. If there
were significant oil-bearing deep breaks there, then oil, due to its lightness, would appear in the mantle. Therefore, the primary object of exploration is deep horizons under large oil fields.

Keywords: oil fields, deep structure of the earth’s crust, fluids.

The purpose of the work: development of a method that will allow us to determine the quantitative indicators of some colour characteristics of gem stones.
Methodology of the research: the study of the absorption spectra of gem stones, the identification of patterns and the development of mathematical tools for quantitative estimate the lightness parameter.
Results. The dependence of the lightness of a gemstone is established by the relative magnitude of light absorption in the zone of the absorption band caused by the main element-chromophore. Mathematically, the characteristic proportional to the optical density of the gemstone is determined, which can be used to quantify its lightness. The nonlinearity of the scale of this characteristic is shown in comparison with the colour groups or lightness indicators accepted in Russia and the USA. Examples are given that reveal the approaches to quantifying the colour of various gem stones with allochromatic colour.
Conclusion. Measurement of the spectral characteristics of gem stones allows us to quantify the indicators of their lightness. For the practical application of this technique, it is necessary to determine the colour standards and the subsequent graduation of the scale. The accuracy of measurements depends on several factors; the main being the sample size. To improve the accuracy of determining the lightness of large gem stones, it is necessary to increase the number of measurements.

Keywords: gemology, gem stones, spectrometer, absorption spectrum, light absorption, colour hue, lightness, chromophore.
