Love that open Volcanic country! I am going to have to google up what Oncoids are though.. They look awesome! Thanks for sharing!
Found out!!
"Oncolites are sedimentary structures formed out of oncoids, which are layered spherical growth structures formed by cyanobacterial growth. Oncolites are very similar to stromatolites, but instead of forming columns they form approximately spherical structures.[1] Often the oncoids form around a central nucleus, such as a shell particle,[2] and the calcium carbonate structure is precipitated by encrusting microbes. Oncolites are indicators of warm waters in the photic zone, but are also known in contemporary freshwater environments [3]. These structures rarely exceed 10 cm in diameter"
Thanks Snownymph, you taught me something new today!
