Porphyry copper deposits are among the most significant sources of copper globally, accounting for over 60% of the world’s copper production . 1. Geological Overview a) Geological Background Porphyry copper deposits are typically associated with magmatic arcs related to subduction zones, where an oceanic plate subducts beneath a continental or another oceanic plate. This tectonic […]Table of Contents Toggle 1. Geological Overviewa) Geological Background
Introduction Ore-bearing hydrothermal fluids are one of the most important agents in the formation of mineral deposits. These fluids, which originate from various geological processes, have the ability to dissolve, transport, and deposit metals in economic concentrations. The study of hydrothermal fluids is crucial for understanding ore genesis and guiding mineral exploration. This article provides […]Table of Contents Toggle Introduction1.

Introduction Alteration in geology refers to mineralogical, textural, and chemical changes in rocks due to interactions with fluids, temperature variations, and pressure changes. This process occurs in diverse geological settings, including hydrothermal systems, weathering environments, and metamorphic terrains. Understanding alteration is essential in mineral exploration, petrology, geotechnical engineering, and environmental studies. This article explores the […]Table of Contents Toggle IntroductionTypes and Processes of Alteration
Introduction The Induced Polarization (IP) method is one of the most effective geophysical techniques used in the exploration of sulfide ore deposits. This method is particularly useful for identifying disseminated sulfide minerals, which are commonly associated with copper (Cu), gold (Au), silver (Ag), zinc (Zn), and lead (Pb) deposits. This article provides a detailed overview […]Table of Contents Toggle Introduction1. Understanding the Induced Polarization ...
Introduction Gold exploration is a complex process that requires a combination of geological knowledge, geochemistry, and geophysical techniques. One of the most effective methods for locating gold deposits is the identification of pathfinder elements and minerals. Pathfinder elements and minerals are geochemical indicators that suggest the presence of gold nearby, even if the gold itself […]Table of Contents Toggle IntroductionWhat Are Pathfinders for Gold Deposits?
Introduction Structural control is one of the most significant factors influencing the formation and distribution of hydrothermal gold deposits. Structural geology determines the pathways for mineralizing fluids, the locations of ore deposition, and the overall geometry of gold-bearing zones. Understanding these structural controls is essential for exploration geologists seeking new gold deposits and for mining […]Table of Contents Toggle IntroductionStructural Controls in Hydrothermal Gold Deposits
Introduction to Geology Geology, derived from the Greek words geo (Earth) and logos (study), is the scientific discipline dedicated to understanding the Earth’s composition, structure, processes, and history. It seeks to answer fundamental questions: How did mountains form? Why do volcanoes erupt? What clues do rocks hold about ancient life? From the atomic structure of […]Table of Contents Toggle Introduction to Geology
Engineering geological tests are critical for assessing the physical, mechanical, and chemical properties of rocks and soils to ensure safe and cost-effective design of infrastructure (e.g., dams, tunnels, foundations). These tests help determine material strength, stability, permeability, and susceptibility to hazards like landslides or subsidence. Below are key tests categorized by their application: 1. Field […]Table of Contents Toggle 1. Field Tests (In-Situ)2. Laboratory Tests
Sand Dune Landform: Formation, Types, and Significance Sand dunes are dynamic landforms created by the interaction of wind, sand, and vegetation. These striking natural features are common in deserts, coastal regions, and even in some semi-arid and arid zones.

Sand and clay are two types of sedimentary materials that differ in their particle size, mineral composition, and other physical properties.
Sand is a granular material composed of rock fragments, minerals, or shells that range in size from 0.063 to 2 millimeters. Sand particles are generally larger than clay particles and can be seen with the naked eye. Sand is often found on beaches and in deserts, and it is commonly used as a building material and in construction projects such as concrete and asphalt.
Clay, on the other hand, is a fine-grained sedimentary material that is composed of minerals such as mica, feldspar, and quartz. Clay particles are smaller than sand particles, with a diameter of less than 0.002 millimeters, and are typically not visible to the naked eye. Clay is often found in soil and is used for making pottery, bricks, and other ceramics.
In terms of physical properties, sand is typically more porous and allows for better drainage, while clay is more cohesive and tends to hold water and nutrients better. Sand is also less fertile than clay and has less nutrient-holding capacity. Clay soils can be difficult to work with because they are sticky when wet and hard when dry, while sand is more easily manageable.
Overall, sand and clay differ in their particle size, mineral composition, and physical properties, and are suited for different uses and applications.
