Volume 15, Issue 2 , April 2024, , Pages 557-579

https://doi.org/10.22044/jme.2023.13446.2482

Abstract
  The aim is to use the Concentration-Volume (C-V) fractal model to identify high-quality parts of coal seams based on sulfur and ash concentrations. In the K1 and K7 coal seams in the North Kochakali coal deposit, 5 and 6 different populations of ash and sulfur content were obtained based on the results. ...  Read More

Volume 10, Issue 4 , October 2019, , Pages 929-945

https://doi.org/10.22044/jme.2019.8374.1716

Abstract
  The traditional approaches of modeling and estimation of highly skewed deposits have led to incorrect evaluations, creating challenges and risks in resource management. The low concentration of the rare earth element (REE) deposits, on one hand, and their strategic importance, on the other, enhances ...  Read More

Determination of geochemical anomalies and gold mineralized stages based on litho-geochemical data for Zarshuran Carlin-like gold deposit (NW Iran) utilizing multi-fractal modeling and stepwise factor analysis

F. Aliyari; P. Afzal; J. Abdollahi Sharif

Volume 8, Issue 4 , October 2017, , Pages 593-610

https://doi.org/10.22044/jme.2017.5252.1340

Abstract
  The Zarshuran Carlin-like gold deposit is located at the Takab Metallogenic belt in the northern part of the Sanandaj-Sirjan zone, NW Iran. The high-grade ore bodies are mainly hosted by black shale and cream to gray massive limestone along the NNE-trending extensional fault/fracture zones. The aim of ...  Read More
