An ophiolite is a section of oceanic crust and upper mantle that has been uplifted and exposed above sea level due to tectonic processes. Ophiolites are important geological features because they provide a window into the Earth’s interior and allow scientists to study the composition and structure of the oceanic crust and upper mantle, which […]
Metamorphic rock is a category of rock that undergoes significant changes in its mineral composition and texture during the process of metamorphism. This transformation occurs due to the high pressure and temperature conditions experienced deep within the Earth’s crust. Metamorphic rocks play a crucial role in understanding the Earth’s geological history and the formation of […]
The Cone Penetration Test (CPT) is a widely used in-situ testing method in geotechnical engineering for determining the geotechnical properties of soils. The CPT provides continuous or semi-continuous data on soil stratigraphy and properties such as soil type, relative density, shear strength, and other parameters relevant to foundation design and soil behavior analysis. CPT Procedure […]Table of Contents Toggle CPT ProcedureUses of CPT Data
Geology 101 is the study of the Earth and its materials, structures, processes, and history. It is a broad field that encompasses many different disciplines, including mineralogy, petrology, paleontology, and geophysics. Geologists study the Earth’s physical features, including its rocks, minerals, soils, and water. They also study the Earth’s internal structure and the processes that […]Table of Contents Toggle Why Study Geology?What Do ...
Rock Quality Designation (RQD) is a measure used in geotechnical engineering to assess the quality of rock core samples. It is calculated by measuring the length of intact pieces of rock in a core sample that are longer than 10 cm. RQD stands for “Rock Quality Designation,” and it is a measure used in geology […]
Geological Time Scale The geological time scale is a system of chronological measurement that relates geological events and geological time to a numerical scale. It is used to describe the timing and relationships between events that have occurred throughout Earth’s history. The time scale is divided into four main parts: Eons, Eras, Periods, and Epochs.

Lithification is the complex process by which loose sediment grains become compacted and transformed into solid rock[1]. This process may occur at the time of sediment deposition or later[1]. The main processes involved in lithification are compaction and cementation[1][2]. Compaction involves the squeezing of sediment grains into a smaller volume by packing them more closely […]Table of Contents Toggle Sources:
The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions which have generally been imposed at depth below the surface zones of weathering and cementation, and which differ from the conditions under which the rocks in question originated. Metamorphism means to “change form,”. In other words, metamorphism is a process that […]Table of Contents Toggle Process of MetamorphismWhat are ...
Introduction Atterberg Limits are crucial parameters in geotechnical engineering and soil science that characterize the physical state and behavior of fine-grained soils, particularly clays. Developed by Swedish chemist Albert Atterberg in the early 20th century, these limits provide insight into how soil behaves under varying moisture conditions. Understanding Atterberg Limits helps engineers and scientists classify […]Table of Contents Toggle Introduction
Basalt forms when magma cools and solidifies on the surface of the earth. It mainly occurs on the floor of the ocean as magma solidifies quickly coming in contact with cool ocean water. On the other hand, granite occurs above the ocean and makes up much of continental crust.
most of the ocean floor is basalt, and most of the continents are granite. Basaltic crust is dark and thin and heavy, while granite is light and accumulates into continent-sized rafts which bob about like corks in this “sea of basalt.” When a continent runs into a piece of seafloor, it’s much like a Mac truck running into a Volkswagon. Not very pretty, but at least there’s a clear winner. And the seafloor basalt ends up in pretty much the same position as does the VW – under the truck (or continent, as the case may be). This may seem like a drag for the basalt, but remember that it isn’t all that happy on the surface anyway, and this gives it the heat it needs to re-melt and try to complete the differentiation process which was so rudely interrupted at the spreading ridge. If successful and allowed to continue, what’s left behind is a “purified” magma with most of the iron, magnesium, and other heavy elements removed. When it cools, guess what forms? And the continental land mass just got a wee bit larger.

Basalt and granite are two different types of rocks that are formed through different geological processes.
Basalt is a dark-colored volcanic rock that is formed from the solidification of lava flows. When molten lava erupts from a volcano and flows over the surface of the earth, it cools and solidifies quickly, forming a fine-grained rock with a dense, uniform texture. Basalt can also be formed from magma that cools underground and solidifies to form intrusive rocks.
Granite, on the other hand, is an igneous rock that is formed from the slow cooling and solidification of magma beneath the earth’s surface. This process can take millions of years and allows for the formation of large crystals within the rock. Granite is typically composed of a mixture of minerals, including quartz, feldspar, mica, and hornblende, and can have a wide range of colors and patterns.
Both basalt and granite are important rocks that have many uses, including construction materials, decorative stones, and as a source of mineral resources.
