Xa kwi-geology sithetha ngobume nokwakhiwa koqweqwe lomhlaba, akunakuphepheka ukuthetha ngezihlungulu. Iifolds zezona zinto zixhaphakileyo ezichaphazela zonke izinto zejoloji. Ezona zaziwa kakhulu zezi I-anticline kunye ne-syncline. Ngesi sizathu, siza kunikezela eli nqaku liphela ukuba lithethe ngezakhiwo ezibalulekileyo kunye neempawu zeentlobo ezahlukeneyo zempinda kunye neempawu zazo.
Ukuba ufuna ukwazi ngakumbi malunga ne-anticline kunye ne-syncline fold, le yiposti yakho.

Zintoni iifolda
Iifolokhwe azikho ngaphezu kwezakhiwo ezenziwa ngenxa yokuguqulwa kwezinto ze-geological. Kubalulekile ukongeza ukuba ezi zinto zisongwayo azivelisi ukophuka. Ezi zakhiwo zejoloji zenziwa ngohlobo lweplastiki olwenziwe ngalo Uxinzelelo loxinzelelo lweetectonic, zombini uxinzelelo kunye nokwanda.
Ukuba sikhumbula yonke into enxulumene Amacwecwe eTectonic Siyabona ukuba umhlaba uqweqwe ngamacwecwe eetectonic ahlukileyo kwaye awalungiswanga. Kukho iminxeba Ukuhanjiswa kwemisinga yengubo eyenza iipleyiti ziqhubeke ngokuqhubekekayo kwaye sesi sizathu sokuba amazwekazi aqhubeke nokuhamba. Ke ngoko, ii-folds zenziwa ngenxa yobukho bezinto ezahlukeneyo ngeplastiki okanye ngokuziphatha okungakhubazeki njengamatye e-sedimentary.
Iinxalenye zesibaya
Isongelo ngalinye linamacandelo abalulekileyo ahlalutyiweyo. Amagqabi ziinqwelomoya ezenza icala. Amacwecwe ama-2 ayadingeka ukwenza ifolda. Eli candelo linokutolikwa njengoko ulandela umphezulu apho izinto zibekwe khona.
Elinye icandelo lesibaya yi-axis okanye ihenjisi kwaye ngumgca ohambelana nokugoba okukhulu kwesibaya kwaye kwenziwa kukudibana phakathi Amacala kunye neelayile ezahlukeneyo okanye umphezulu wesahlulo. Inqwelomoya ye-axial yenye yecandelo lesibaya kwaye lenziwa sisiphambuka phakathi kwemigca yee-axes zoluhlu ngalunye lwesibaya. Kuxhomekeka inqwelomoya yezihlunu kwisibaya ngasinye, iya kuba nee-angles ezahlukeneyo zokudipha.
Ulwahlulo lweefolda
Ngoku siza kuthetha ngeentlobo ezahlukeneyo zeefolda ngokobunjani bazo kunye nokumila kwazo. Kukho iindlela ezininzi zokuhlela iifolokhwe kwaye ezona zixhaphakileyo zezi zinxulumene nendlela apho izinto eziphambili zijolise khona. Inqwelomoya, i-axis kunye ne-engile phakathi kweeflanzi zezona zinto zenza umahluko phakathi kolunye udidi nolunye.
Uhlobo lokuqala esinalo luhambelana nemilo yalo. Olu luhlu lwahlulwe lwaba: I-anticline kunye ne-synclinal fold. Kukho ulungelelwaniso olulinganayo. Ukwahlulahlulahlula okwesibini kusekwe kukuntywila kwendiza ye-axial: apha sinotyekelo, ukujika kunye nokuxoka. Ngokwe-axis yesihlwitha sinesilinda kunye nesiciko.
Olunye udidi olungasetyenziswanga ngokubanzi ngabo basebenzisa i-engile phakathi kwamalungu. Nazi ezi folda zilandelayo:
- Ithembekile, i-angle ye-interlimbal engaphezulu kwe-120 °
- Vula isibaya, i-engile ye-interlimbal 70 ° ukuya kwi-120 °
- Vala usonge, 30 ° ukuya kuma-70 °
- Umxinwa omxinwa, i-10 ° ukuya kwi-30 ° i-engile ye-interlimbal
- Isoclinal fold, i-angle yangaphakathi phakathi kwe-0 °
I-Anticline kunye ne-syncline
Uluhlu lwe-anticline luphawulwa ngokuba nesimo se-convex ukuya phezulu. Kungenxa yokuba izinto ezincinci ezenza isibaya ziphezulu, ngelixa izinto ezindala zisisiseko. Kukho amaxesha apho singakwaziyo ubudala bemathiriyeli kwaye kwezi meko kubhetele ukubiza esi sakhiwo njenge ichaseneyo.
Kwelinye icala, sine-synclinal fold. Olona phawu lwayo luphambili kukuba iyahambelana ukuya phezulu. Kungenxa yokuba ezona zinto zincinci zisembindini, ngelixa ezindala zenza ezantsi. Ngendlela efanayo ne-anticline fold, ukuba asazi ukuba zindala kangakanani izinto, kungcono ukubiza olu lwakhiwo njenge engenazimilo.
Xa sihlela uhlobo lwesibaya ngokungqinelana nokudipha kwenqwelomoya ye-axial kufuneka sithathele ingqalelo uhlobo lwe-engile esinayo. Kwezi meko sifumana ulingano, utyekelo, ukujikajika kunye nokugoba. Zonke ezi folda zinoluhlu oluphakathi kwe-0 degrees kunye ne-90 degrees.
Iifolda ezilinganayo yilezo apho i-engile eyenziwe yindiza ye-axial ilingana kumacala omabini. Kule meko, i-engile eyenziwayo ngenqwelomoya ye-axial ime nkqo. Olunye udidi lwesibaya luthambekele ngohlobo lokuba elinye lamagxa ane-engile enkulu yokudibanisa ngokubhekisele kwenye.
I-Morphology ye-anticline kunye ne-synclinal fold
Siza kuqala ukuchaza uluhlu lwe-anticline. Iziko layo line-axis macala. Amacala amabini e-anticline abonisa iindlela ezahlukeneyo zokuthambeka. Umtya uhlala uncike kwiiflanzi. Ukusuka embindini usiya emacaleni i-manto iyanda kancinci. Imanteo, nangona kunjalo, embindini incinci okanye inguziro.
Siyaqhubeka nokuchaza ifolda yokuvumelanisa. Iziko li-axis ye-symmetry. Amacala amabini e-syncline abonisa iindlela ezahlukeneyo zokuthambeka. Uluhlu lwangaphakathi lwangaphakathi luhlala luxhomekeke kwi-nucleus. I-manteo, kule meko, ikwanguziro. Uluhlu oluncinci luvela embindini kwaye endala indala ishiyeke ecaleni.
Ukuze ukwazi ukubona ezi folda kwiimephu zejoloji kulula njengokuchonga ukuphindwaphindwa kolingano lwezixhobo ngokubhekisele kwi-axis esembindini. Le yindlela yokuhlangana kwendiza ye-axial kunye nomhlaba ongaphezulu. Kolu phinda-phindo lwezixhobo akufuneki sithathele ingqalelo ukugqabhuka kwezixhobo. Oku kungenxa yokukrwela kunye nokuqina komphezulu wezixhobo Kuxhomekeka kwinqanaba lokuntywila kwezixhobo kunye nomphezulu esikuso.
Njengoko ubona, wonke umba weefolda yinto enzima kakhulu. Ndiyathemba ukuba ndiye ndanceda ukufumanisa i-anticline kunye ne-syncline folds kwimephu ye-geologic.
