Natural resource geology Tectonic belts in Mongolia have a strong influence on where base metal ores have formed. The East Mongolian Metallogenic Province covers two-thirds of the country and was highly influenced by Mesozoic magmatic activity. The South Mongolian Metallogenic Province is a third grouping.
What are Precambrian fossils?
The Precambrian (prior to 541 million years ago) was the “Age of Early Life.” Soft-bodied creatures like worms and jellyfish lived in the world’s oceans. Common Precambrian fossils include mats of algae called stromatolites, microorganisms, and simple animals.
What geologic events happened in the Precambrian era?
This era began with the formation of the earth from dust and gas orbiting the Sun about 4.6 billion years ago. During this era the surface of the Earth was like popular visions about Hades: oceans of liquid rock, boiling sulfur, and impact craters everywhere!
What was the Precambrian era known for?
The Precambrian is the earliest of the geologic ages, which are marked by different layers of sedimentary rock. Laid down over millions of years, these rock layers contain a permanent record of the Earth’s past, including the fossilized remains of plants and animals buried when the sediments were formed.
Why are there so few trees in Mongolia?
Environmental issues. In the winter the grass becomes dry and very flammable, making wildfires more common. Grass recovers quickly from the fire, but, trees do not. This partially explains the absence of trees in the area.
What is the climate of Mongolia?
Mongolia has a high elevation, with a cold and dry climate. It has an extreme continental climate with long, cold winters and short summers, during which most precipitation falls. The country averages 257 cloudless days a year, and it is usually at the center of a region of high atmospheric pressure.
Are jellyfish Precambrian?
Jellyfish were probably the first muscle-powered swimmers in the open ocean. They appeared in the late Precambrian Era, a period of major geologic and ecological changes that preceded the Cambrian explosion of animal life.
What happened in the Cambrian period?
The Cambrian period, part of the Paleozoic era, produced the most intense burst of evolution ever known. The Cambrian Explosion saw an incredible diversity of life emerge, including many major animal groups alive today. Among them were the chordates, to which vertebrates (animals with backbones) such as humans belong.
What evidence do we have of Precambrian life?
The earliest evidence for the advent of life includes Precambrian microfossils that resemble algae, cysts of flagellates, tubes interpreted to be the remains of filamentous organisms, and stromatolites (sheetlike mats precipitated by communities of microorganisms).

What tools do Geologists use to collect samples?
Geologists spend a lot of time in the field collecting samples to study. In order to collect samples the geologists works with many of the same tools as the archeologist. They use: handpicks, brushes, pointed bricklayer’s trowel , hand shovel, dustpan, whisk broom, stakes, string, cameras, notebooks and pencils.
