The analytical problems of dating gypsum speleothems with the U-series technique are reviewed.
Gypsum speleothems are, in general, very low in U content, challenging the limits of detection methods.
Types of speleothems include: Speleothems may also occur in lava tubes.
Although sometimes similar in appearance to speleothems in caves formed by dissolution, these are formed by the cooling of residual lava within the lava tube.
chronology with near pinpoint accuracy in previous research over the years in their state-of-the-art Radiogenic Isotope Laboratory at UNM that Asmerom leads, they were equipped to date the delicate florets that adhered to the top of Naia's body after she fell in the cave.

Speleothems take various forms, depending on whether the water drips, seeps, condenses, flows, or ponds.
