    Calcarenite is a sedimentary rock formed of calcareous particles that have been deposited mechanically from a solution. The particles which consist of fossil materials, pebbles and granules of carbonate rock and Oolites are transported and sorted by flowing water. When it is formed entirely of shell debris the rock is called coquina. (Robert 1768) 1.1. Composition of calcarenite Calcarenite is a type of limestone composed mainly of above 50% of detrital sand of size 0.0625 to 3mm in diameter in

    History of asbestos. There are four main types of asbestos; Amosite (brown fibers), Anthophyllite (gray fibers), white Christie, and blue Crocidolite.

They can adhere to skin or clothing and are easily swallowed or inhaled. Half a century ago, asbestos was hailed by many as a miracle product. They said nearly anything could be made from this mineral. It as

    ANCIENT EUROPEAN ART Prehistoric and Primitive Art: Paintings in the prehistoric era i.e. during 1400 to 9500 BC were generally done in huge limestone caves that served as habitation. Cave paintings have been discovered in Northern Spain and Dordogne Valley of South-West France. The Paleolithic art that flourished in this region is termed as the Franco-Cantabrian school. The paintings during this period were done for magico-religious purpose. The art of the Franco-Cantabrian school consists entirely

    1. Introduction: The geologic cycle consists of three cycles which collectively play a role in the formation of the materials and processes on earth; the tectonic cycle, rock cycle and hydrological cycle. It is a continuous system involving many different aspects which must work together to achieve a natural balance. These cycles exchange energy and matter and whenever this occurs there is the potential for environmental damage due to extreme conditions (Nelson, 2016). The concept of uniformitarianism

    Comparing rocks Minerals make up rocks. Rocks are formed in many environments upon and within the Earth's crust. There are three types of rock, each formed in a different `way. Igneous rock , formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks, formed from the products of weathering by cementation or precipitation on the Earth’s surface. Metamorphic rocks , formed by temperatur e and pressure changes inside the Earth.

    Weathering and erosion are two processes that sort of shape Earth’s ground and rocks. Weathering is either a mechanical or chemical process that breaks down or shapes rocks, while erosion transports the leftovers of weathering, away. Understanding these processes helps us understand the way lakes, rivers, mountains, shorelines, canyons, and all sorts of other things were formed. For example the Grand Canyon was formed by erosion created from the Colorado River. It is very important to understand

The canyon, at its deepest is about 6,000 feet and at its widest it about 18 miles. According to the article I read, the canyon is a record of “deep” time, which means, it’s old. Powell and other geologists, knew there were three sections or “sets” of rocks that are exposed in the Grand Canyon

Two rock types are from the Tertiary and the Quaternary period and are starting to intrude into the older rock types. The outer laying rocks are dipping away from the center at an angle with a slope dipping 5 degrees. Jewel Cave’s rock type was formed in the Pennsylvanian-Permian Minnelusa Formation, between the Pennsylvanian and Missippian period. (See Figure 4). Jewel

    The Grand Canyon is a notable topographic feature in Northern America. It has nearly 2, 000 meters of rock layers exposed on the surface with twelve major rock units and occupies a region of broad continental crust. Despite its vastness, how it exactly became as it is now remains a question to scientists who study the area. The Grand Canyon is located specifically at the southwestern edge of the Colorado Plateau in Arizona. It begins at Lee’s Ferry and ends at the Grand Wash Cliffs. It reaches up

    Introduction Rose quartz is a pale pink to rose-red variety of quartz. Quartz is the second most plentiful mineral found in the Earth’s crust. Rose Quartz occurs only in massive formations, with no crystal faces, edges or points. It is often hazy or turbid; therefore it lacks good transparency. It also contains microscopic fibers, which can on occasion produce a cat’s eye or star effect within the stone. Rose quartz crystals are formed when the pressure within the earth pushes molten lava into
