I think quartz
Halite can scratch gypsum.
Bedded gypsum and halite are sedimentary rocks that form in evaporite environments. Gypsum is a soft mineral composed of calcium sulfate, while halite is composed of sodium chloride. These rocks typically form in arid climates where evaporation rates exceed precipitation, leading to the deposition of salts and minerals.
Gypsum and halite both form through the evaporation of water, leading to their distinct cubic crystal structures. This process results in a uniform distribution of their mineral composition, contributing to the unlayered and homogeneous appearance of these minerals.
It will depend in what is in the water, in general it will be the solids that have been dissolved, but they will come out as crystals if evaporated slowly. in general it will be salt and/or limescale (calcium carbonate) as they are easily soluble
The mineral form of NaCl is halite. Halite is a common mineral that is often found in sedimentary rocks and in evaporite deposits.

These rocks typically form in arid climates where evaporation rates exceed precipitation, leading to the deposition of salts and minerals.
Halite is a mineral composed of sodium chloride, commonly known as table salt, while gypsum is a mineral composed of calcium sulfate. Halite is typically clear or white in color, while gypsum is usually white or colorless with a pearly or glassy luster. Additionally, halite is soluble in water, while gypsum is only slightly soluble.
Rock salt and rock gypsum are predominately the minerals halite and gypsum respectively. Quartzite is also predominately the mineral quartz.

Halite can scratch gypsum, which has a Mohs hardness of 2.5 on the Mohs scale. Halite has a hardness of 2.5, so it can scratch any mineral with a hardness lower than 2.5.
Common examples are: calcite, calcium carbonate, halite, sylvite, gypsum etc.
The mineral form of NaCl is halite. Halite is a common mineral that is often found in sedimentary rocks and in evaporite deposits.
Calcite typically effervesces in acid, whereas halite and gypsum do not. Halite is salty to taste, while gypsum is softer and can be scratched with a fingernail. Also, halite forms cubic crystals, while gypsum forms tabular crystals.
Gypsum and Halite are both formed from the body of salt-water.
not a hydrogenous sediment?
