(A) Outcrop of the Buena Vista Fm in Sink 13LM south of La Muerta, with a hand lens for scale. Erosion of the algal mats has emphasized prominent bedding. The limestone is light grey on weathered surfaces but cream-colored on a fresh surface. The rock is poorly cemented and soft, but exposed surfaces have a harder crust. (B) Microphotograph of sample 19-095B, located in Sink 13LM as shown in Fig 12A. This laminated, pedogenic carbonate consists of wavy laminated, algal/rhizolithic mats (AM) interlayered with microporous, chalky caliche (CC) layers. The algal mats contain common calcified filaments (CF) and root molds (RM). The chalky caliche consists of microcrystalline calcite formed through the pedogenic alteration of limestone bedrock. Traces of limestone intraclasts are present. Root penetration and other pedogenic processes brecciated the caliche crust. Moldic pores (MO) and micropores are common in the algal/rhizolithic mats, and intracrystalline pores are common in the chalky caliche layers. |
