source: Furthermore, spectroscopic studies have shown evidence of hydrated minerals and silicates, which indicate rather a stony surface composition.
target: Furthermore, spectroscopic studies have shown hydrated minerals and silicates have a stony surface.
references: Furthermore, spectroscopic studies have shown hydrated minerals and silicates have a stony surface. Chemistry studies show minerals and silicates with water attached show a stony surface makeup. Studies splitting light have indicated a rather stony surface. Stectroscopic studies have shown evidence of hydrated minerals and silicates, which indicate a stony surface composition. Studies using light show that the surface was made of stones. Furthermore, spectroscopic studies have shown evidence of hydrated minerals and silicates, which indicate a stony surface composition. Also, spectroscopic studies have shown evidence of moist minerals and silicates, which indicate a rocky composition on the surface. Spectroscopic studies show evidence that indicates a stony surface composition. Also, spectroscopic studies showed that there were hydrated minerals and silicates. This tells us that the surface composition is stony. Spectroscopic studies show the existence of hydrated minerals and silicates.  This means that there is a stony surface composition.
