Limestone composed of the mineral calcite undergoes dissolution in acids. In other words, it effervesces dramatically when we apply dilute HCl. Limestone is a permeable rock type, so the water that runs down the bluffs gets soaked into the rock and takes mineral deposits with it. This causes mineral staining on limestone bluffs to be far less prominent than that of sandstone bluffs; the vertical streaks often start at the top of the bluff and disappear a short distance down.A mineral's streak is the color it has when ground to a powder. Some minerals that occur in a range of colors always have the same streak. As a result, streak is considered a more stable indicator than the color of the solid rock.
