Orthorhombic
Niahite, an ammonium manganese phosphate hydrate mineral, was identified from Sterling Hill, where it occurs associated with newberyite, sussexite, and severely altered pyrochroite. It was verified using X-ray methods and a microprobe wavelength-dispersive scan which showed Mn and P as the major elements. Niahite occurs as 0.3 mm pearly crystals, isolated, and whitish-pink. It has not been found at Franklin.
