The survey zone corresponds to the Sirba greenstone belt, one of Liptako Birimian Formations (LBF) Niger. Previous aeromagnetic and geochemical works reveal significant gold occurrences. present study integrates geophysical mapping these occurrences by electromagnetic induction on field. A multi-frequencies system 10 frequencies was used for depth subsurface investigation resistive anomalies. i...

The Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...

Oil and gas reservoir has long-term suffering from hydrocarbon seepages including macroseepages and microseepages. The presence of seepages documents the first element of a hydrocarbon system and could therefore reduce exploration risks. Hydrocarbons that escape from underground reservoirs cause oxidation-reduction reactions either in situ or along vertical migration pathways and result in anom...

There are many small and medium-sized orogenic copper deposits in the Jinman–Lanping area of Yunnan. In order to standardize mining, long-term planning, unified management, it is necessary further delineate prospecting areas. improve efficiency prospecting, a data-driven approach established. This paper uses weight evidence model make predictions, then delineates prospective area. The relevant ...

purpose: to assess the frequency and type of associated malformations and chromosomal anomalies among patients with anophthalmia, microphthalmia, and coloboma in sistan and baluchestan province. methods: patients with a clinical diagnosis of anophthalmia, microphthalmia, or coloboma were examined to find any anomaly in craniofacial, muscle-skeletal, cardiac, neurologic and urogenital systems. a...

in this descriptive study, researchers determined rate and type of newborn infants’ anomalies in rafsanjen niknafas hospital in 1991-1995.  this study is resulted from medical records of mothers referring to above mentioned center during five years. total number of child birth was 21187. 17321 was normal vaginal delivery and 3866 was cesarean section. because of unknown reasons, 57 infants were...

Lithium is considered a critical metal for its technological use. It was proposed to carry out the geochemical prospecting study in favorable environments host possible lithium mineralization, specific sectors of Ecuador. This would be important, as no anomalies economic interest have been discovered date. The content Li solid samples and hydrothermal waters brines Guaranda sector, Bolívar prov...
