Phyllosilicates

Mr. COWEN: To one of these interesting places where they have found these what they call phyllosilicates, which are really clays that have been formed in the presence of water. ❋ Unknown (2010)

We detected for the first time a type of mineral called phyllosilicates on the surface of ❋ Unknown (2010)

In at least nine, they found clays and clay-like minerals called phyllosilicates, or other hydrated silicates that form in wet environments on the surface or underground. ❋ Unknown (2010)

Many of these exist in the form of hydrated clay minerals known as phyllosilicates, and indicate that the planet's southern hemisphere was once much warmer and wetter than it is today. ❋ Unknown (2010)

He explained that these instruments had revealed clay-type minerals called phyllosilicates ❋ Unknown (2010)

But we'd now like to go to a place where these phyllosilicates, as they call them, have really been exposed by big impact craters. ❋ Unknown (2010)

The visual said finegrained schist with phyllosilicates all the way down. ❋ Willis, Connie (1994)

Morris and her colleagues began by modeling the infrared emission features of dust that did not contain hydrated minerals, or phyllosilicates. ❋ Unknown (2010)

It would be an especially difficult task if phyllosilicates only make up a small portion of the disk material, or if a variety of phyllosilicate minerals are present. ❋ Unknown (2010)

Morris says the outcome of this study shows only that, based on the computer models, it should be possible to detect the presence of phyllosilicates in protoplanetary disks. ❋ Unknown (2010)

One of the simplest examples of phyllosilicates is clay minerals. ❋ Unknown (2010)

A recent study published in the journal Astrobiology described using infrared spectroscopy to model the dust surrounding young extrasolar stars to try to detect the presence of hydrous minerals called phyllosilicates. ❋ Unknown (2010)

Earlier observations with the OMEGA spectrometer on Mars Express had tentatively detected phyllosilicates in a few craters of the northern plains, but the deposits are small, and CRISM can make focused observations on smaller areas than OMEGA. ❋ Unknown (2010)

Therefore, if phyllosilicates are found in the protoplanetary disk of a young extrasolar star, the assumption is that water would most likely be found on the surface of planets that are later born within the disk. ❋ Unknown (2010)

They then changed the mineral mixture by adding phyllosilicates amounting to three percent of the total mixture. ❋ Unknown (2010)
