According to scientific theories, moldavites innervisioncrystals.net/fake-moldavite formed at Stuttgart (southwestern Germany), 148,000 years ago.
Calculations and laboratory simulations have led to the conclusion that this meteorite measured 500-1000 meters in diameter (1640-3200 ft.). It is most likely that the meteorite was from the west-southwest at a sharp angle (30-50deg).
The meteorite’s impact created a large crater measuring 25 km (15.5 mi) in diameter. Ries Kessel. The impact caused the meteorite to split into smaller pieces. The existence of a smaller crater, measuring 4km (22.5 mi) in diameter, proves this. Steinheim. Ries Kessel is located at 30km (18.6 miles). Scientists believed the Ries Kessel Crater was formed from a volcano remnant. The crater contains Coesite, a rare quartz variety. It was formed by heavy smelting and pressure from a meteorite hit.
The meteorite traveled at 22 km/s (13.7mi./s) through the Earth’s atmosphere. The meteorite’s flight through the atmosphere saw temperatures rise to 5 000 – 10 000degC (9,000-18,000degF) on the forward-facing surface; pressure 500GPa
Following the meteorite’s impact, kinetic energy was transferred to melt the meteorite and underlying rocks. They then catapulted into the upper atmosphere layers. The atmosphere melted the melt, which became glassy and congealed. Drops of the melted mixture fell onto Czech Republic territory and were washed to sediments. Moldavites current deposits relate to these Tertiary sediments. The impact angel determined which direction the meteorite dropped in and the distance between the meteorite impact and the melted moldavites was approximately 450 km (280 mi). Fall field is the name given to the area where molted moldavites are impacted.
Moldavites were then washed in secondary fields from various localities.
