Why is sandstone porous and quartzite not?
sandstone has rounded grain so the water can get into a gaps between the grain quartzite have interlocking crystals
Which layers are composed of sediments of the largest grain size?
conglomerate
Which sedimentary rock has the coarsest grain flint or limestone or sandstone?
== == The "coarseness" of a sedimentary rock refers to the rock's textural character, and more particularly, the size of grains contained within it. Thus, a conglomerate containing pebble or cobble clasts is coarser than a sandstone containing sand grains. In the same way, a conglomerate containing boulders is coarser than a conglomerate containing pebbles. Clastic sedimentary rocks are classified using the Wentworth Scale. The coarsest elements of this scale are the Rudites. Boulder rudites are conglomeratic rocks with grains of diameter greater than 256mm. They are the coarsest element described on the Wentworth Scale. There is no upper limit to the scale of sedimentary coarseness, since the size of clast which can be preserved in a sedimentary rocks is potentially very large. 'Olistolith' is a term which describes very large clasts often derived from the sub-sea collapse of oversteepened slopes such as are found at continental margins. Sediments containing olistoliths may reasonably be described as the coarsest sedimentary rocks.
What is the particle size of clastic sedimentary rocks?
Shale is composed of the smallest particles of other rocks.
What is Dissolution and Recrystallization?
•Cementation •Dissolution of minerals, followed by precipitation around grain boundaries •Makes a sand a sandstone
Why is sandstone porous and quartzite not?

Which layers are composed of sediments of the largest grain size?
conglomerate
Is sandstone grain fine?
Yes it is fine grained.
What determines the grain shape of a rock such as conglomerate?
The mineral composition of the conglomerate determines the grain shape as well the the type of weathering or erosive elements (wind, water, chemicals) that the rock is is exposed to because grain shape is heavily dependent upon whether the rock has been subjected to erosion or not.
What is the Grain size of conglomerate?
Course grained it mean more than 2 mm.

Which has the largest grain size the rocks made from mud clay or the ones made from sand?
Sandstone is the classification of rock composed of small rounded rock particles, usually quartz in nature.
What minerals make up conglomerate?
Hi there, a conglomerate is actually a crock where the dominant grain size is larger than a certain size. From memory it is 5mm. A conglomerate can be made from any mineral assemblage. www.aapg.org is a good place to find out more
The smallest rock is a grain of what?
Rock.
Is a grain of sand the smallest rock?
no
What sedimetary rock has the smallest grain size?
*
What is the particle size of clastic sedimentary rocks?
Shale is composed of the smallest particles of other rocks.
