Agate is a microcrystalline variety of quartz, chiefly chalcedony, cryptocrystalline form of silica.  Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks but can be common in certain metamorphic rocks. Most agates occur as nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly  by siliceous matter deposited in regular layers upon the walls.

Limestone is chemically a calcium carbonate formed by accumulation of biogenic remains or precipitation from chemical solution. This limestone was probably formed ina lake environment when changes in the depositional condition resulted in formation of a carbonate ooze at the bottom of the lake that was later converted into limestone layers.
