- In mineralogy, having an even lamellar or flatly foliated structure.
Diamond, sir, in extraordinary evidence! in conjunction with specular iron ore, commonly called the red haematite, and the ferrous carbonate, or spathic iron.
Siderite or spathic iron ore occurs as a gangue mineral in some of the gold quartz veins in the central part of the State, but owing to its limited quantity, it is of little economical importance for the manufacture of iron.
The mineralogical character of the iron ores found in the State includes magnetite, red hematite, brown hematite (limonite), siderite (spathic ore), and black band ores.
Again, many minerals, such as crystals, are bounded by plain surfaces, and, with very few exceptions (spathic and hematite iron and dolomite are such exceptions) none are bounded by curved lines and surfaces, while living organisms are bounded by such lines and surfaces.
Throughout the coal-measures of the commonwealth there are vast beds of spathic ore, which will serve when the more available deposits have been exhausted.

At Pillersee, in Austria, spathic iron ore has been reduced by a mixture of fir-wood charcoal, and air-dry peat in the proportions of three parts by bulk of the former to one of the latter.
It contains, as substances accidentally disseminated in the mass, brown iron-ore, spathic iron, even rock-crystal.
The property of the spathic acid, to corrode flinty substances, has been lately applied by a Mr. Puymaurin, to engrave on glass, as artists engrave on copper, with aquafortis.
