WebGabbro: Vesicular Basalt: Gabbro is a coarse-grained mafic igneous rock, made with mainly mafic minerals like pyroxene and only minor plagioclase. Because mafic lava is more mobile, it is less common than basalt. Gabbro is a major component of the lower oceanic crust. Basalt is a fine-grained mafic igneous rock. It is commonly vesicular and ... WebSep 27, 2024 · The Au 3+ ion, because of its higher positive charge, is a harder acid than Au + and can form complexes with harder bases such as H 2 O and amines. In keeping with the "like binds like" principle, the compound AuI (soft-soft) is stable, but AuI 3 (hard-soft) is unknown. Conversely, AuF has never been isolated but AuF 3 (hard-hard) is stable.
