Dark conglomerates

Zhang Y, Baumeister U, Tschierske C, O Callaghan MJ, Walker C (2010) Achiral bent-core molecules with a series of linear or branched carbosilane termini dark conglomerate phases, supramolecular chirality and macroscopic polar order. Chem Mater 22 2869-2884... 

Besides the Bn nomenclature phases, bent-core molecules also display other phases such as SmAP, hexagonal Col phases (Colh), and dark conglomerate (DC) phases.

The geology in the project area mostly comprises black to dark grey shale inter-bedded with sandstone and conglomerate of the Cretaceous Saniri Formation (Kim and Hwang 1986). This sedimentary sequence has been intruded by thin to very thick, near-vertical dykes and sills of quartz porphyry. The slope section under consideration is shown in Figure 1(a).
