Ing Batúng kaliús, o petrified wood king Ingles (ibat kareng katayang "batú" ampong "kaliús", metung a uri ning pun dutung, ing Streblus asper), metung yang clasing fossil: bibilugan ne ning fossil a dutung nung nu deng eganaganang sangkap a organicu, miyalilan lang mineral (keraklan metung a silicate, antimo ing quartz), kabang manatili ing orihinal o sadiang pangabalangkas ning dutung. Maliliari king lalam ning gabun ing procesu ning pamanalili king batú o petrifaction. Mitatambunan ya king lalam ning palák (sediment) ing dutung, at king umpisa, e masisira iti uling king kakulangan ning oxygen. Magdalang mineral kareng cell ning tanaman ing danum a dakal melasong mineral, at kabang malalaso la reng lignin ampong cellulose ning tanaman, ating molding gawá king batúng lalto king lipat da reti. 

Keraklan, mági yang batúng kaliús ing dutung kilub ning dinalan (100) a banua. Kailangan nang ma-petrify ning sangkap a organicu bayu ya laganas a malaso. 

Mirinan yang miayaliwang kule ing batúng kaliús uling kareng elementung manganese, bakal ampong tangsu king danum kabang maliliari ing procesu ning petrifaction. Ala lang kule deng purung cristal a quartz, dapot nung ating misasamut a aliwang sangkap, mikaka kule lang dilo, malutu o aliwa pa deng cristal. 

Ing makatuki lista de reng elementung misasamut (contaminating elements) ampo deng kuleng bibie da reti:
 carbon - matuling
 cobalt - aluntian/iro (azul)
 chromium - aluntian/iro (azul)
 copper - aluntian/iro (azul)
 iron oxides - malutu, komanggi (brown), ampong dilo
 manganese - malare (rosas o pink)/dalandan
 manganese oxides - matuling/dilo

Malalakuan king batúng kaliús ing orihinal nang pangabalangkas o istructura ning dutung, pati na ing sabla nang detalle, angga king lebel a microscopic. Maralas lang mayayakit deng dake antimo deng tree ring ampo reng miayaliwang tissue.

Maki Mohs hardness yang 7 ing batúng kaliús, kapareu ning quartz.

Ing batúng kaliús ing batu nang panlalawigan ning Alberta, ampo ing iyas nang pang-estadu ning Washington.
