Cone-in-cone structures Wikipedia
Cone-in-cone structures are secondary sedimentary structures that form in association with deeper burial and diagenesis.They consist of concentric inter-bedded cones of calcite or more rarely gypsum, siderite or pyrite. Although several mechanisms may be responsible for the formation of cone-in-cone structures, displacive crystal mechanism is preferred.

Oct 15, 2011· The creek itself rarely contains cone in cone structures due to the swift water current. The creek bed itself is pretty much solid bedrock, smooth and slippery. Large deep pools of crystal clear water flow down into Lake Erie itself. Most, if not all cone in cone structures will be found on the banks, in silt, sand and rock deposits.
Conifer cone Wikipedia
A cone (in formal botanical usage: strobilus, plural strobili) is an organ on plants in the division Pinophyta that contains the reproductive structures. The familiar woody cone is the female cone, which produces seeds.The male cones, which produce pollen, are usually herbaceous and much less conspicuous even at full maturity. The name "cone" derives from the fact that the shape in some

Cone Structure and Function Photoreceptors
Physically, cone cells are conical shaped structures that are generally thicker and shorter than rods. In mice, the outer segment of a cone cell is about 1.2 microns in diameter and 13 microns in length, whereas they are 1.4 microns in diameter and 24 microns in length for rods (Engel et al., 2009).
