Lithology and environment
Primary lithology: | shelly/skeletal "carbonate" |
Includes fossils? | Y |
Lithology description: "Shells commonly occur in swell-lags, which means concentration without long-distance transport." | |
Environment: | marine indet. |
Geology comments: "...calm, open marine, microtidal, shallow, commonly swept by storms, transitional to a barrier or interbarrier system in shoreface region...blue-green alga...micritized shell fragments...The general environment seems to suggest BA 3 to 2 [but certain elements present here, such as Clorinda, are known to extend deeper]. Thus a BA 1 to 5 assignment might be indicated." |
