Sten, mineraler og fossiler: for alment interesserede læsere

Due to unprecedented growth in population and the resultant massive mining of energy resources, especially the non-renewable resources and also water resources, these resources have gradually become scarce commodities. Hence the geoscientists and the technocrats from all over the world have embarked into many fold research programmes for locating newer reservoirs of these resources and also to develop models to conserve and sustainably exploit them. As this involves the total understanding of the rock types, tectonic architecture, geomorphology and reservoir conditions, the Geomatics technology comprising Remote Sensing, Geographic Information System (GIS), etc have been found to be vital tools in the inventory and management of these resources; While the former due to its synoptivity, multispectral nature and repeativity and the latter by virtue of its capability to store, manipulate and model huge volume of spatial and non-spatial data. Divergent geological provinces and processes are brought out deserving concepts and methods on geology, 3D visualization of subsurface lineaments, SRTM based lineament mapping, spatio-linear modeling of hard rock aquifer systems, 3D visualization of oil bearing structures, etc., both as field geologists and as researchers.

This is the go-to instructional guide for the beginner rockhounder and prospector.

"Despite their fame and reputation, dinosaurs represent only half the story of the Mesozoic Era. In Beast Companions: The Unsung Animals of the Dinosaurs' World, paleontologist John Foster explores the often-overlooked animals that coexisted with them. These ancient species, often equally remarkable as their dinosaur neighbors, can provide valuable insights into the biotic history of our planet. In some cases, these animals reveal just as much, if not more, about the extinct ecosystems of the time as the dinosaurs themselves.By drawing on a wealth of current and past discoveries, Foster embarks on a sweeping journey across 164 million years to visit the beast companions of the dinosaurs. Along the way, he examines fish, insects, the first frogs and salamanders, turtles, snakes and lizards, marine reptiles, crocodiles, pterosaurs, birds, mammals, and other animals of the Mesozoic Era.Beast Companions is a groundbreaking exploration of the story of these contemporaries of the dinosaurs that set the modern world in motion more than 200 million years ago"--

A fossil expedition becomes a thrilling search for a mythical beast deep in the Indonesian forest - and a fascinating look at how fossils, folklore, and biodiversity converge.The need to understand and conserve biodiversity has never been more pressing. This is particularly urgent for vulnerable ecosystems such as islands, which have suffered human-caused extinctions throughout history and recent prehistory.A tale of exciting scientific discovery, The Tomb of the Mili Mongga is based on the story of expeditions to the island of Sumba in eastern Indonesia. While there, Professor Samuel Turvey discovers an entire recently extinct mammal fauna from the island's fossil record, revealing how islands support some of the world's most remarkable biodiversity, and why many endemics are threatened with extinction.But as the story unfolds, a new narrative emerges - Sumba's indigenous communities tell of a mysterious wildman called the mili mongga, a giant yeti-like beast that supposedly lives in the island's remote forests. What is behind the stories of the mili mongga? Is there a link between this enigmatic entity and the fossils Sam's looking for? And what did he discover when he finally found the grave of a mili mongga?The Tomb of the Mili Mongga combines evolution, conservation, anthropology, travel writing and cryptozoology to explore the traditional culture and unique biodiversity of a tropical island that's largely unknown to the outside world. It also considers wider questions about the relationship between biodiversity and cultural diversity, what reality means from different cultural perspectives, and how folklore, fossils and biodiversity conservation can be linked together in surprising ways.

The process of preparing bricks using mine waste involves mixing the waste materials, such as fly ash and bottom ash, with clay and other binding agents to create a homogeneous mixture. The mixture is then pressed into molds and allowed to dry and harden. The resulting bricks have several advantages, including lower costs, reduced environmental impact, and improved structural properties. The use of mine waste in brick making also helps to reduce the volume of waste produced by mining operations, making it a more sustainable practice. This process has the potential to make a significant contribution to sustainable construction and waste management practices.The use of mine waste in brick making has gained increasing attention in recent years due to the increasing demand for sustainable construction materials and the need for effective waste management practices. The mining industry generates a significant amount of waste materials, such as fly ash and bottom ash, which are often disposed of in landfills or ponds. However, these waste materials have the potential to be used as raw materials for brick making.The process of preparing bricks using mine waste involves several steps. The waste materials are first collected and transported to the brick manufacturing site. The waste materials are then mixed with clay and other binding agents to form a homogeneous mixture. The proportion of mine waste to other ingredients in the mixture may vary depending on the quality and quantity of the waste material.Once the mixture is prepared, it is then pressed into molds using hydraulic or manual presses. The molded mixture is then allowed to dry and harden, either through air drying or by using a kiln. The resulting bricks are then ready for use in construction.
