The stages of geological map preparation
In this part, in addition to becoming familiar with the profession of geologists, you will also learn about geological maps, how they have been prepared from the past to the present, and the methods of research in the geosciences.
volcano
A volcano is a geological structure through which volcanic materials (in the form of molten lava, gases, solid fragments, or a combination of all three) ascend from the Earth’s interior to its surface. The accumulation of these materials at the point of ejection forms elevations known as volcanic mountains.
The Facade of the Earth Science Park Museum
Museums are inherently intertwined with art and creativity. Around the world, there is constant competition to showcase items that embody artistic and creative expression within museums. However, at times, visitors may overlook the deeper message behind an exhibit.
Rock Cycle
In geology, the rock cycle constitutes a foundational conceptual model that elucidates how lithologic materials evolve across geological time through the interplay of tectonic processes, sedimentation, erosion, and metamorphism.
Herbivorous Dinosaur
In 1878, a gigantic fossil was discovered in the state of Colorado. This dinosaur, named *Diplodocus*, had a very long neck and tail, and its body length reached 28 meters. Many scientists believe that Diplodocus is the longest dinosaur in the world.
Fluorescence Minerals
Fluorescence is a special optical property in our world. This phenomenon is rarely observed in some species of animals and plants in nature. In simple terms, fluorescence occurs when ultraviolet (UV) light shines on a material, causing electronic transitions between energy levels, which then results in the emission of a visible colored light with high brightness. To observe fluorescence, two conditions are essential: the presence of ultraviolet light and darkness.
Fault benches
The presentation of various types of faults in the form of fault benches is one of the scientific attractions of the geoscience park.
Earthquakes in Iran
Iran is one of the regions with high seismic potential in the world. However, the distribution of earthquakes across the country is not uniform.
Building Stones
A major portion of the world’s mines—as well as those in Iran and, consequently, in Razavi Khorasan Province—consists of building stones, ranging from igneous rocks and rubble stone to dimension stone and marble. In Razavi Khorasan Province, out of 632 active mines, about 340 are related to rubble and building stones. In other words, in terms of quantity, more than 50 percent of the mines fall within the category of building stones.
The Eatrh
The Earth is divided into three main layers based on the differences in the chemical properties of its constituent materials: the crust, mantle, and core.
Rocks
In this gallery, igneous, metamorphic and sedimentary rocks are presented in a diverse collection and scientifically categorized.
Statues of the Geologist and Mother Earth
Alongside the specialized and thematic exhibits, museums often incorporate artistic elements and installations to enhance their appeal. One such artistic piece is the Statue of the Geologist, installed at the entrance of the Earth Science Park Museum in Mashhad.
Mining tunnel
This exhibition tunnel is a reconstruction of the Tabas coal mine, with an approximate length of 300 meters, designed to replicate the actual environment of a coal mine.
Geogenic diseases and their origins
The origin of all elements is the Earth, and both natural and anthropogenic contaminants can transfer from rocks and soil to water, plants, and livestock, and ultimately enter the human body through the food chain.
Ore
On the museum visit path, the ore deposits collections display various ores in the form of twenty five showcases,
Precambrian
The earliest geological era is the Precambrian, which began 4.6 billion years ago and lasted until 542 million years ago.
Paleozoic
The Paleozoic is the second geological era, beginning 542 million years ago and continuing until 241 million years ago.
Meteorite
A meteorite is a rocky or metallic body that enters the Earth's atmosphere from space. Its high-speed movement through the atmosphere generates frictional heat, causing the object to glow and produce the luminous trail known as a "meteor" or "shooting star." A large portion of the meteorite may burn up in the atmosphere, but fragments that reach the Earth's surface are called meteorites (United States Geological Survey, USGS).
World Seismotectonic Map
Seismotectonics is a branch of geology that studies the relationship between seismic phenomena and the Earth's tectonic structures and processes.
The Polarizing Light Microscope in Petrography and Paleontology
The polarizing light microscope (PLM) is one of the key instruments used in petrological, mineralogical, and paleontological studies. By utilizing polarized light, it can reveal fine structures and mineral textures that are not visible to the naked eye.
Solar System
Astronomy has always been one of the subjects of human interest that especially children and teenagers are attracted to this subject.
Mesozoic
The Mesozoic is the third geological era, lasting approximately 186 million years, from about 251 to 65 million years ago.
Land Subsidence
Vertical downward movement of the Earth's surface is referred to as land subsidence.
Sundial
A sundial is a device that measures local time during the day by using the position of the sun in the sky. The most common type of sundial consists of a rod (gnomon) placed on a flat surface, with the hours of the day marked on the surface. As the sun’s position in the sky changes, the shadow cast by the rod moves across the surface, indicating the time.
