A homoclinal ridge ko strike ridge ne wani tudu ko ridge tare da wani matsakaici, gabaɗaya tsakanin 10 ° da 30 °, karkata baya. Yankin baya shi ne gangaren Ruwa, wanda ya dace da raguwar wani tsari mai tsayayya ko strata, wanda ake kira Caprock. A wancan gefen ɗayan gangaren, wanda shine gabansa, na tudu mai laushi ne mai tsayi ko ma mai kama da dutse (ƙwanƙwasawa) wanda aka kafa ta hanyar fitowar caprock. Dutsen yana yankewa ta hanyar shimfidar wuri wanda ya ƙunshi tudun homoclinal.[1][2]
Homoclinal ridges sune furcin yanki na matsakaiciyar nutsewa, yawanci sedimentary strata, wanda ya kunshi gadaje masu sauyawa na wuya, da kyau-lithified strata, watau sandstone da limestone da raunana ko mai laushi strata, wato shale, mudstone, da marl. Yankin dutse mai tsayayya da rushewa ya zama caprock na baya (dip-slope) na tsaunuka na homoclinal wanda rushewa ta fi dacewa ta cire duk wani sashi mai rauni. Kayan da ke gaba, gabansa, wanda ke samar da gaban wani tsaunin homoclinal ya ƙunshi wani tsauni wanda ya yanke a fadin gado da ke kunshe da shi. Saboda yanayin nutsewa na matsakaici na strata wanda ke samar da tudu na homoclinal, wani gagarumin canji a wuri a kwance zai faru da wuri mai faɗi ya saukar da rushewa.[3] Saboda gangaren tsaunuka na homoclinal yana nutsewa a cikin wannan gefen kamar yadda yake a ƙarƙashinsa, ana iya lissafin kusurwar nutsewa na wannan gado (Ө) ta hanyar v / h = tan (Ө) inda v daidai yake da nisan tsaye kuma h daidai yake da nesa a kwance a tsaye zuwa yajin gado.
Cuestas, homoclinal ridges, da Hogbacks sun ƙunshi jerin siffofin ƙasa waɗanda ke samar da ci gaba na gradational. Wadannan siffofin ƙasa sun bambanta ne kawai a kan tsawo na baya da bambance-bambance na dangi a cikin karkatawar baya da gaba. Wadannan bambance-bambance sun dogara ne akan ko nutsewar sassan da aka rushe su kusan kusan tsaye ne, nutsewa a matsakaici, ko nutsewa cikin hankali. Gabaɗaya, tuddai na homoclinal, ko tuddai na yajin aiki, suna da alaƙa da ɓangarorin da ke nutsewa tsakanin 10 ° da 30 °. Yankunan da ke nuna alamun hogbacks suna tasowa inda strata ke nutsewa sosai a 40 ° ko fiye. Saboda suna da gradational a yanayi, ainihin kusurwar baya da aka yi amfani da shi don bayyana waɗannan siffofin ƙasa yana da son rai kuma yana iya bambanta a cikin wallafe-wallafen kimiyya.[3][4][5]
