Where are septarian nodules found?
Septarian nodules, sometimes called lightning stones, can also found on the Lake Michigan shoreline as well as in New Zealand, England, Morocco, and Madagascar. Septarians are composed of calcite (the yellow centers), aragonite (the brown lines), and limestone (the outer grey surface).
What is a siderite septarian nodule?
Siderite nodules are not the only concretions in the Eagle Ford Formation. There are also septarian nodules, which are the result of dewatering of the sediments, which causes cracks to form, and the subsequent deposition of minerals to fill the crack spaces.”
What is Utah septarian?
Septarian nodules are concretions containing angular cavities or cracks. Septarians were formed during the Cretaceous period, 50 to 70 million years ago when the Gulf of Mexico reached what is now Southern Utah. They mine the septarians in Southern Utah then, cut and polish them in their garage.
What is a septarian sphere?
Although often called septarian nodules, this sedimentary rock is more technically a concretion. A concretion is a spherical, egg shaped, or irregular mass that forms around a nucleus. Madagascan septaria are gray to brown limestone with yellow calcite and brown to black aragonite. Some pieces have colorless baryte.

There are several active leases, and most of the best nodules come from 20-30 feet underground where they are mined with the assistance of excavators. Utah septarian has fairly distinctive and sometimes fairly large, honey-colored, yellow calcite crystals. About 25-30% of the nodules have hollow cavities inside of them.
What kind of minerals are found in Septarian Nodules?
Barite crystals, pyrite and marcasite are also minerals frequently seen in septarian nodules. It’s not unusual to find the remains of marine fossils inside of septarian nodules, though they are rarely well preserved.
Is it possible to find marine fossils in a Septarian nodule?
