Gold Basin - L4 Ordinary Chondrite - Complete Slice - 10.51g - USA (Arizona)

A 10.51g complete slice of Gold Basin, presented in a frame display with a collection card showing the Arizona desert where the meteorites are found. The polished face shows the brown, weathered L4 interior with chondrules and fine metal grains.

Gold Basin is a well-known L4 Ordinary Chondrite meteorite found in Mohave County, Arizona, USA. First recognised in the 1990s, it became one of the most important American meteorite strewn fields, with thousands of individual stones recovered across a wide desert area. Its L4 classification places it within the low iron Ordinary Chondrites, while the type 4 grade indicates moderate thermal alteration that has preserved many Chondritic features.

Specimens of Gold Basin often show a weathered brown exterior from long exposure in the desert environment, with interiors that can reveal chondrules, metal grains, and brecciated L Chondrite material. Many pieces have a natural desert-polished appearance, while cut sections can show the internal texture more clearly. Studies of the strewn field suggest an ancient fall, often described as a ‘fossil’ meteorite field, with a terrestrial age of around 15,000 years.

For collectors, Gold Basin offers a classic and well-documented USA meteorite with strong provenance and broad appeal. Its Arizona origin, large strewn field, and availability in a range of specimen types make it popular for display, study, and collection building. Each specimen represents ancient asteroid material formed over 4.5 billion years ago, preserved in one of North America’s most recognised meteorite finds.
