Helium-4 mostly arises from alpha decay of heavy radioactive elements. Helium-3 is primordial helium, and is extremely rare on Earth. Whether or not a minute proportion of the Earth's total helium-4 is regarded as primordial depends very much on the context of the particular article.

what's the meaning of primordial helium?
Primordial helium refers to the helium that was formed during the Big Bang nucleosynthesis, approximately 3 to 20 minutes after the Big Bang. This process produced about 25% of the universe's mass in helium, along with hydrogen and trace amounts of other light elements. Unlike helium produced in stars (stellar helium), primordial helium is a remnant of the universe's early conditions and is found in the interstellar medium and as part of the cosmic background. It plays a crucial role in understanding the universe's evolution and the formation of cosmic structures.
What is primordial material?
Primordial material refers to the original matter that existed in the early universe before the formation of stars and galaxies. This material mainly consisted of hydrogen and helium, which were created during the Big Bang. Over time, through processes like nuclear fusion in stars, this primordial material has transformed into the various elements we see in the universe today.
What is a reasonable explanation for presence of helium gas in erths crust?
Helium gas in the Earth's crust primarily originates from the natural radioactive decay of uranium and thorium, which produce alpha particles that eventually capture electrons and form helium atoms. Additionally, helium can be trapped in natural gas deposits and released during geological processes. Some helium is also thought to be primordial, having been formed during the Big Bang and retained in the Earth's crust over billions of years. These processes contribute to the presence of helium in various geological formations.
