ʻO ka pōhaku pele (ʻike mau ʻia ʻo ka pumice a i ʻole ka basalt porous) he mea hana a pili i ke kaiapuni, ʻo ia ka pōhaku porous makamae i hana ʻia e ke aniani lua pele, nā minerala, a me nā ʻōpū ma hope o ka lua pele.Loaʻa i ka pōhaku pele he mau haneli o nā minerala a me nā mea e like me ka sodium, magnesium, aluminum, silicon, calcium, titanium, manganese, hao, nickel, cobalt, a me molybdenum.ʻAʻole ia he radiative a loaʻa nā hawewe magnetic infrared mamao.Ma hope o ka lua pele aloha ʻole, ma hope o nā ʻumi kaukani makahiki, ke ʻike nui nei ke kanaka i kona waiwai.I kēia manawa ua hoʻonui ʻo ia i kāna mau noi noi i nā kula e like me ka hoʻolālā, mālama wai, wili, nā mea kānana, barbecue charcoal, landscaping, soilless cultivation, a me nā huahana hoʻonaninani, e pāʻani ana i kahi kuleana i hiki ʻole ke hoʻololi ʻia i nā ʻoihana like ʻole.

ʻO Basalt kekahi ʻano pōhaku Pelekani maʻamau, ʻo ia ke ʻano o ka pōhaku paʻa a i ʻole ka ʻūhā i hana ʻia e ka pelemaka mai ka lua pele ma hope o ka maʻalili ʻana o ka ʻili.No ka pōhaku magmatic.Hōʻike pinepine kona ʻano pōhaku i nā ʻano stomatal, ʻalemona, a me nā hale porphyritic, i kekahi manawa me nā kristal mineral nui.He ʻeleʻele a hina hina ka basalt unweathered, a he ʻeleʻele ʻeleʻele hoʻi, poni ʻeleʻele, a me ka ʻōmaʻomaʻo hina.

ʻO ka porous basalt (pumice), ma muli o kona porosity kiʻekiʻe a me ka paʻakikī nui, hiki ke hoʻohui ʻia me ka paona e hōʻemi ai i kona kaumaha, akā ikaika nō naʻe a loaʻa nā ʻano e like me ke kani ʻana a me ka wela wela.He hui maikaʻi ia no ka ʻuala māmā ma nā hale kiʻekiʻe.ʻO ka pumice ka mea wili maikaʻi, hiki ke hoʻohana ʻia e wili i nā mea metala a me nā mea pōhaku;Ma ka 'oihana, hiki ke hoʻohana 'ia e like me nā kānana, nā mea maloʻo, nā catalysts, etc.
