Is Antimony a sedimentary metamorphic or igneous?
Antimony (atomic symbol=Sb) is a metallic, valuable ore element that commonly occurs in association with silicic volcanic or subvolcanic magmatic (igneous) systems. Antimony may also be anomalously enriched in black graphitic shales.
What terms Takes place when magma intrudes rock?
When magma intrudes into existing rock, the process is known as "igneous intrusion." This can lead to the formation of various types of igneous rocks, depending on the composition and cooling rate of the magma. The surrounding rock is often altered by heat and pressure, creating metamorphic features. Common forms of igneous intrusions include plutons, sills, and dikes.
Is emerald an igneous rock?
No, Emerald is a variety of the mineral beryl (Be3Al2(SiO3)6,) colored green by trace amounts of chromium and sometimes vanadium and not an igneous rock. However beryl crystals form in association with Granite intrusions (which are Igneous rocks) and are often associated with tin and tungsten ore bodies in what are called pegmatities. They are also to be found in mica schists which are metamorphic rocks and also uniquely, the emerald deposits in Colombia Colombia are in limestone, a sedimentary rock.
Is gold often found in the vewins of quartz that are in and around igneous intrusions?
It is released at the end of magma crystallization in a hot, mineral-rich fluid that fills cracks and voids in the surrounding rock. This fluid solidifies to form metal-rich quartz veins.by aidan
Valuable ore deposits and gem crystals are often associated with?
Valuable ore deposits and gem crystals are often associated with hydrothermal processes that involve the circulation of hot fluids through rocks, creating conditions for mineral deposition. These fluids can carry and deposit valuable minerals such as gold, silver, and diamonds in fractures or cavities within the rocks. Such deposits are commonly found in areas with active or ancient volcanic activity and tectonic activity.

Why are mineral deposits often found around the perimeter of igneous intrusions?
Mineral deposits are often found around the perimeter of igneous intrusions due to the process of hydrothermal alteration, where hot, mineral-rich fluids generated by the cooling magma migrate through fractures in the surrounding rock. As these fluids cool and react with the surrounding rocks, they can precipitate valuable minerals. Additionally, the temperature and pressure conditions around the intrusion create a favorable environment for the concentration of certain minerals, leading to the formation of ore deposits. This spatial relationship is commonly observed in various mining districts worldwide.

What landform do all the states with silver deposits have in common?
Many states with silver deposits have mountainous regions in common. These mountainous areas often contain geological formations that are conducive to silver mineralization, such as fault lines, veins, and igneous intrusions.
Would you expect a light gray igneous rock to be rich or poor in silica?
I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.

Is batholith tabular or massive?
Batholiths are typically massive igneous rock formations that often extend over large areas. They are formed from the solidification of magma deep within the Earth's crust. While they may have tabular intrusions within them, the overall structure of a batholith is considered massive.
What ore deposits and gem crystals are often associated with?
Ore deposits are often associated with hydrothermal processes, where minerals are deposited from hot fluids circulating in the Earth's crust. Gem crystals are often found in igneous and metamorphic rocks, where the conditions for their formation are present, such as high pressure and temperature.
