SIR —Observing that the " ConeinCone " controversy still goes on in the GEOLOGICAL MAGAZINE I beg you will permit me to remark in this connection that the question whether this puzzling formation occurs on both sides of slabs and nodular masses of calcareous rocks clayironstone etc. whether the apices of the layers of cones point upwards as well as downwards or not was set at
Coneincone structures were chosen for this work mainly for the reasons that they exhibit a character which would suggest a compressive origin on a scale small enough to study in handspechnen and that from previous descriptions of their morphology they would appear to be inconsistent with the results of the photoclastic study.
semitropical genus and there is no warrant for attributing to it as Dr. Blanford does a capacity for living under conditions like those of the Hnndes plateau. The only species of Ehinoceros known to me which were the companions of the Horse etc. etc. elsewhere were the B. antiquitatis and the B. Merchii to one of which I believe the remains probably belonged. My view in regard to the
Typically these cone in cone structures form with the large open end of the cone on the top of the bedding plane and the apex or pointed end of the cone

coneincone structure A secondary sedimentary structure consisting of small cones nested one inside another and most commonly made from calcium carbonate. They are believed to form by the growth of fibrous crystals in the sediment while this is still plastic. Source for information on coneincone structure A Dictionary of Earth Sciences dictionary.
On 1/7/2019 at 7 43 PM Brett Breakin Rocks said The ol cone in cone ploy ehhhh You guessed it a cone in cone structure caused by growth of calcite crystals during diagenisis. I showed it to several persons with geology degrees most thought that it was a fossil such as coral. Only one guessed correctly.

The cones are usually at right angles to the sedimentary layering or bedding. The ridges on the side of the cone become less pronounced near the apex. Growth of fibrous crystals in layers results in vertical pressures in the rock causing small breakages. As pressure continues the breakages overlap causing the steppedcone structures.
Previous theories on coneincone structure origin have failed to explain some of its features such as the absence of coneincone in veins other than horizontal and the crosscutting relations of conical surfaces to detritical clay films. They have neither taken in account the importance of pore pressures in the process of growth of veins and concretions nor the effects of its fall in the
The cone structures are of two types those in concretions and calcitecemented sandstone composed of plumose aggregates of fibrous calcite and those in lenses of coneincone composed of microgranular calcite. Origin of the first is due to the growth and precipitation of fibrous calcite during early diagenesis and the microgranular texture

Coneincone structures are strange features found as interbeds in finegrained siliciclastic rocks and sometimes found in the outer layers of concretions. They consists of sets of conical structures stacked up within each other. Mineralogically they are often composed of finelycrystalline fibrous calcite. Numerous hypotheses have been proposed over the years that try to explain coneincone
1. Introduction. Descriptions of coneincone and arguments over its genesis date back to the eighteenth century. The common characteristic that defines the structure is that it is an accumulation of a mineral (usually calcite) comprising fibrous or bladed crystals which form conical aggregates within a rock.

Cones. Cone structures also called spikes or peaks are a typical structure created by the femtosecond laser irradiation of materials. The growing of cone structures is of crucial importance in the ablation effects by femtosecond laser because their geometrical parameters (height periodicity and density of the forest) are directly
Coneincone is a peculiar structure consisting of usually vertical nests of cones one inside another that are found either in thin beds or at the edges of large concretions. Some cones are less than an inch tall and others are as much as 10 inches high. They have a ribbed or scaly appearance. Most coneincone is composed of impure calcium

Coneincone structures are secondary sedimentary structures that form in association with deeper burial and consist of concentric interbedded cones of calcite or more rarely gypsum siderite or pyrite. Although several mechanisms may be responsible for the formation of coneincone structures displacive crystal mechanism is preferred.

Cones are concentrated in the center of our retina in an area called the macula and help us see fine details. The retina has approximately 120 million rods and 6 million cones. There are three types of cone cells Redsensing cones (60 percent) Greensensing cones (30 percent) and Bluesensing cones (10 percent) Eye problems that can affect

The coneincones are thought to have originated from a syngenetic concretion of fibrous aragonite. The conical structures are believed to have formed while the surrounding clay materials were still plastic and that clay was introduced along the major fractures as the coneincone structure developed.
