Principal Types of Folds and Their Field Characters

Principal Types of Folds and Their Field Characters

by Gelogia Team | Jul 20, 2025 | Physical Geology & Geomorphology, Structural Geology

Folds are significant geological structures formed when rock layers undergo compression, resulting in bending without fracturing. They are commonly observed in deformed sedimentary, metamorphic, and even igneous rocks. Understanding the different types of folds and...

James Hutton: Father of Modern Geology

by Gelogia Team | Jul 19, 2025 | Historical Geology, Physical Geology & Geomorphology

James Hutton, usually described as the “Father of Modern Geology,” plays a critical role in the field of Earth sciences. His innovative insights contested prevailing perspectives on the Earth’s history and established the basis for contemporary...
Understanding Fault Zones Under Gravity Dams

Understanding Fault Zones Under Gravity Dams

by Gelogia Team | Jul 17, 2025 | Hydrology, Physical Geology & Geomorphology, Structural Geology

The fault zone lying under gravity dams is composed of weak gouge materials with a low modulus of elasticity as compared to sound rocks, and hence is more deformable. The pressure of a fault zone induces more stress in a foundation than a normal foundation. A fault...
Types of Grouting

Types of Grouting

by Gelogia Team | Jul 16, 2025 | Physical Geology & Geomorphology, Structural Geology

Grouting plays a crucial role in geotechnical engineering by improving the strength, stability, and impermeability of soil and rock foundations. Engineers inject a fluid-like material into voids, cracks, or porous zones to seal, consolidate, or reinforce the ground....

Subsoil Exploration by Drill Holes: Methods and Techniques Explained

by Gelogia Team | Jul 14, 2025 | Physical Geology & Geomorphology, Structural Geology

Subsoil exploration helps engineers understand what lies beneath the ground surface before starting any construction work. It identifies different soil layers and their properties. One of the common ways to explore subsoil involves drilling holes using methods such as...
Soil Compaction

Soil Compaction

by Gelogia Team | Jul 12, 2025 | Physical Geology & Geomorphology, Structural Geology

Compression soil accomplished by loading for a short period is known as compaction. It is a quick process of densification and stabilization of soil. A soil mass loses its compactness when it is excavated from its natural source and deposited elsewhere. Why Soil...
