The Esfordi iron - apatite ore in Central Iran is locAted in Bafq metallogenic province. Stratigraphically most of the rock units belong to Precambrian and Cambrian sequenses which the sedimentary and volcanic series are the most spreading rock types and mineralization took place just within the vOlcanic-sedimentary unit of the mentioned series. Study of REE contents of apatite in Esfordi...
Introduction: A normal sexual desire plays an important role in marital stability; therefore, it is essential to identify factors affecting it. Aim: The present study aimed predict based on emotional self-regulation, experiential avoidance, and depressive symptoms female teachers Bafq, Iran. Method: In this descriptive-correlational study, the statistical population consisted of 225 teachers, w...
The aim of this research was the considering of the impression of the positive couple-therapy on the increasing the life expectancy and marriage closeness of the normal women in Bafq. The way & kind of the quasi-experimental was pre-test –post-test with the group of control. The sample included thirty (30) people that were chosen to target . & were put on the two groups of experiment &con...
The Lakeh-Siah iron± apatite deposit is located in the Bafq-Saghand Metallogenic Province (Central Iran) and situated within rhyolitic rocks. Magnetite with minor apatite are the main ore minerals in this deposit. Monazite and xenotime minerals in microscopic scale formed as inclusion in the apatite and magnetite crystals and micro-fractures. Based on microscopic and EPMA evidences, apatite is ...
The aim of this study is separation of Fe2O3, TiO2 and V2O5 anomalies in Esfordi 1:100,000 sheet which is located in Bafq district, Central Iran. The analyzed elements of stream sediment samples taken in the area can be classified into 5 groups (factors) by factor analysis. The Concentration–Number (C-N) fractal model was used for delineation of the Fe2O3, TiO2 and V2O5 thresholds. According to...
بررسیهای ژئوشیمی و رادیوایزوتوپی برای تعیین خاستگاه آپاتیت در ذخایر آهن و آپاتیت منطقهی معدنی بافق
The iron-apatite deposits of the Bafq mining district contain elevated REE content and occur together with vast alterations in country-rock which were formed due to widespread hydrothermal processes in Early Cambrian. Apatite and rare earth element geochemistry as well as radioactive isotope studies of Sm-Nd show that apatite formation might be due to hydrothermal activities and remobilization ...
Gazestan magnetite-apatite deposit is located in Central Iran and Bafq region, which has been occurred in form of veins, veinlets, and small apatite lenses as well as magnetite in metasomatic rock types such as green chlorite-actinolite rock units. These rocks are situated in the carbonate-volcanic complex of Upper Precambrian-Lower Cambrian Rizo formation. In this study, staged factor analysis...
introduction iron-apatite ore deposits well known as kiruna iron type formed in association with calc-alkaline volcanism from proterozoic to tertiary (hitzman et al., 1992). liquid immiscibility in an igneous system was proposed to explain the formation of the iron oxides accompanying apatite in mineralized zones (förster and jafarzadeh, 1994; daliran, 1999). the mode of ore formation however, ...
