The chemical formula of mineral Arsenoflorencite-(La) is indicated by (La,Sr)Al3(AsO4,SO4,PO4)2(OH)6. This mineral was named as the arsenic analog of florencite and the dominant rare earth element, Lanthanum. Arsenoflorencite-(La) is known to crystallize in the trigonal system of crystal formation.

            Mineral Arsenoflorencite-(La) is most commonly found colored white in hand sample. The specific gravity measure of mineral Arsenoflorencite-(La) is usually found 4.15 grams per cubic centimeters. Most crystals of mineral Arsenoflorencite-(La) are found transparent in appearance. The hardness measure of the mineral is usually found 3.5 when evaluated using the Mohs scale method. Mineral Arsenoflorencite-(La) is usually found exhibiting vitreous or glassy luster when viewed in reflected light of polarizing microscope for mineralogists. Arsenoflorencite-(La) is most commonly found leaving a white streak when rubbed on white porcelain streak plate. It is also most commonly found showing uniaxial positive figure when evaluated between crossed nicols of polarized microscope for mineralogists. It also shows 0.0100 birefringence. Arsenoflorencite-(La) has a weak radioactivity detected when it is chemically evaluated.
