Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons (Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago (Ga) to the beginning of the Cambrian Period, about 538.8 million years ago (Ma), when hard-shelled creatures first appeared in abundance.

precambrian
The Precambrian is the geological time period on Earth that extends from the formation of the planet around 4.6 billion years ago to the emergence and proliferation of complex, multi-cellular life around 541 million years ago. It represents approximately 88% of Earth's history and is divided into three eons: the Hadean, Archean, and Proterozoic. The end of the Precambrian marks the beginning of the Cambrian period, characterized by the rapid evolution of life, known as the Cambrian Explosion.

This work may support a renewed interest in sampling ancient iron deposits on Earth (e.g., Precambrian iron formations) to search for evidence of microbial life, regardless of their low organic carbon content, and may support analysis of organics in iron deposits on Mars, such as Hematite Ridge in Gale Crater.
