The area near the Freeden Seamounts over 20,000 km 2 (7,700 sq mi) has a meteorite material surface density of 10–60 kg/m 2 (2.0–12.3 lb/sq ft). Of this, 87% is melted and 13% only fragmented. This area is the region of the Earth's surface with the highest known density of meteorite material coverage. [2] The disturbed sediment had three ...
In 2021, evidence for a probable impact 3.46 billion-years ago at Pilbara Craton has been found in the form of a 150 kilometres (93 mi) crater created by the impact of a 10 kilometres (6.2 mi) asteroid (named "The Apex Asteroid") into the sea at a depth of 2.5 kilometres (1.6 mi) (near the site of Marble Bar, Western Australia).

Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
An asteroid that crashed into the Earth’s atmosphere over the UK and France was spotted just hours before it crashed. The world was given only seven hours warning that it was being approached by ...
There, geological evidence of eight impact events, which occurred between 3.6 billion and 3.2 billion years ago, can be found in the rocks and traced through tiny meteorite impact particles called ...

The Massalia asteroid family, formed about 40 million years ago, accounts for a class of meteorites called L chondrites that represent 37% of known Earth meteorites, the research found.
There are several lists of meteorite impacts of various types available: Category:Lists of impact craters contains lists on various planets, including Earth by continent; Meteorite falls are observed; Meteorite finds are rocks found on the ground which are geologically identified as meteorites; Meteorite contains lists of the most notable of ...
