Detrital clastic pōhaku: ano, ano a me ka Mea Maluna

Terrigenous hoʻomāhuahua nā pōhaku a i hanaʻia e like me ka hopena o ka'ōpala hoʻi neʻeʻana a me ka haawi aku - me mechanical particulate nā minelala hao fracture ma kekahi mau hana o ka makani, ka wai, ka hau, kai eʻe. Ma nā hua'ōlelo, ka decomposition nā huahana o ka mālama '-nei kuahiwi papa koa, a ma muli o ia ka luku undergone Nine Inch, a ma paʻi aʻe, a laila, koke i loko o ka waiʻauʻau ia, huli i pōhaku paʻa. Terigennye pöhaku hoike no ka 20% o nā mea a pau sedimentary accumulations ma ka honua, o ka wahi o ka i mea no hoi e lauwili, a hiki i ka 10 km ma ka hohonu o ka honua i ka pńpa. Penei kekahi mau breeds hohonu wahi mea he ololi ma ka hoomaopopo ana i ko lakou 'ole.

Weathering me ke koe o ka ho okumu i ka clastic pōhaku

Ka mea mua a me ka nui mua i loko o ke kahua, he clastic pōhaku luku. Pela ka mea, he sedimentary mea, kūpono ma ka 'ilikai fracture e alalai mai ai ma luna o ka pōhaku magmatic o sedimentary a me ka metamorphic kumu. First mauna i ke kanaka me ia ma paʻi keiki, e like me ńlua, palaoa. Kēia mau mea i ka Nine Inch kaʻina (loli), ma ka no o ka i ana pohaku hoʻoneʻe i loko o nā Hawaii.

Ke weathering o ka waiwai i hoʻokaʻawaleʻia ma luna o ka haku mele 'ana a me ka hele. Ka lewa lau luaipele, Aluminum a me ka hao - ma ka pāʻoihana a me nā colloids, kalipuna, paʻakai, a potasiuma - ma ka pāʻoihana, akā, ka silica i ka hoʻopale i ka noho male 'ana, no laila, e like me pōaka i mechanically hoolilo aku hoi i'ōpala hoʻi, a me nā waikahe.

Aʻanuʻu o ka ho okumu i amo i loko o clastic pōhaku

Ka lua o ke kahua ma i ka hana clastic sedimentary pōhaku, mea, e hoolilo i hana ia e ka weathering o ka hoʻoneʻe makani sedimentaryʻia, ka wai a me ka hauneneʻe. I ka papa kuhikuhiE transporter o (particles) ka wai. Komo 'o ia poe ikehu, ka wai evaporates oiai e neʻe ana ma ka lewa, a me ka moe i loko o ke kinowai ai a paa palapala ma luna o ka'āina, ho okumu i ka muliwai i lawe' ona i loko o kekahi mau Hawaii (mea hoʻoheheʻe, colloidal a paa).

I ka helu a me ke kaumaha o ka mea kaʻi aku koena ai hilinaʻi nui ma ka ikehu, māmā holo a me ka leo o ke kahe ana o ka wai. A hookeai kahawai kaʻi aku one, iliili, a me kekahi manawa iliili, kau mea, ma ka huli, hoolilo i ka palolo (particles). Hauneneʻe, mauna muliwai a me mudflow bulk kaʻi aku paala, i ka nui o ia mau (particles) ihoiho 10 knm.

Sedimentogenesis - he kolu o kaʻanuʻu

Sedimentogenesis - o ka hoʻomāhuahua o kaʻi aku sedimentary me ka ho okumu, ai ka hoolilo (particles) e hele mai i ka hoʻoneʻe ana i ke kūpaʻa. Ma keia hihia i ka Nine Inch, a me mechanical differentiation o ka mea. E like me ka hopena, e hoʻokaʻawaleʻia nā (particles) mua, hoolilo i kākoʻo pāʻoihana a me colloids i loko o ka wai ÿauÿau, ke kaumaha ma muli substitutions ma hoemi i ka oxidative i hoʻolilo 'ia a me ka loli i ka'ōmiko o ke kīʻaha. E like me ka hopena, i ka mechanical e kaawale ana o ka'ōpala hoʻi differentiation ia lŘlŘ ma ke kaupaonaʻana, a hiki i ka nui a me ke ano o ko lākou kekahi kaʻao ka holo. A hoolilo (particles) e waiho uniformly ike, e like me ka ciie? O ka holoʻokoʻa lalo o ka wai puna. Ke'ōlelo mai, no ka laʻana, paala, e waihoia iliili i loko o ka waha o ka mauna muliwai, a? Uyie aa ma ke kae koe iliili, ma waho - one (e like me ka mea i ka nani mahele, a me ka hiki, e hele nui mamao, a me ka? Iaeoe? Wahi nui ma mua o iliili) kŰlń ao ka hahai ana i ka maikai silt, palolo pinepine precipitated.

I ka ha o ka kahua o ka ho okumu - diagenesis

I ka ha o ke kahua o ke kahua o clastic pōhaku ka anu u, i kapaia o diagenesis, i mea o ka huli ana o ka hoʻonui ke kimu ole i loko o ka hana pohaku. Waiho ma ka lalo o ka loko me nā kaʻi aku, hoopaakiki hoi paha wale huli i loko o nā pōhaku. Next, ka sediment loaa ana ma ka aoao maoli likeʻole eiiiiiaiou i hana i ka chemically a dynamically lolelua ka a me ka nonequilibrium kamaʻilio, no laila, na eiiiiiaiou hoʻomaka reacting me kekahi i kekahi. Pepe iho la ka (particles) i ka pilina paʻa silikone'okesaside e i loaa i loko o ka sludge i hele i loko o feldspar, ke aloha precipitates a me ke olonā i lepo i lilo 'i ka ho'ēmiʻana, i ka huli, a hiki i ka hohonu o ka 2-3 knm, Ua hiki hoi ke hoʻololi oxidative meakino ili.

Ka hope ke kahua: ka muli o clastic pōhaku

No ka diagenesis E katagenesis - ke kaʻina hana i loko i loaʻa ua hana metamorphic pōhaku. E like me ka hopena, he e māhuahua pohaku sedimentation undergoes pae hoʻololi i ka wela ma luna a me ka puʻe. Lōʻihi-manawa hopena o ia ka pae ana wela a me ka puʻuwai ka poʻea pau e hoʻoholumua i a me ka hope ho okumu pōhaku a i hope, mai ke kakini i hoʻokahi piliona makahiki.

Ma keia ke kahua, ka mahana moku'āina o 200 kekelē Kelekia ma redistribution nā minelala hao a me ka nuipa a ho okumu o hou mea pōhaku waiwai. Pēlā nō clastic pōhaku, examples no i mea i loko o kēlā kihi kēia kihi o ka poepoe honua.

kalepona pōhaku

Ka ua hoʻopili clastic a me ka kalepona pōhaku? Ke pane He poe noonoo ole. I ka haku mele 'ana o ka kalepona pinepine mai nā' clastic (fragmental a me ka pālolo) huihui ikehu lā. Walaʻauʻana kalepona nā minelala hao o sedimentary pōhaku i dolomite a me ka calcite. Ka mea, e ia kekahi kaawale paha pu, a me kā lākou mau hiʻohiʻona, he manawa okoa. Ua pau hilinaʻi nui ma luna o ka manawa a me ka ano o ka ho okumu ana o kalepona sediments. Inā terrigene, ahu iho i loko o ka pōhaku, ua oi aku ma mua o 50%, ia mea,ʻaʻole he kalepona, a pili i na clastic pōhaku me silts, 'Ohi, grits a me ke one, a laila clastic huihui ikehu lā doped me carbonates, me ka like ana o ka i mea i ka 5%.

Mea Maluna o clastic pōhaku i loko o ke degere o ka roundness

Clastic pōhaku, Mea Maluna ua nānā 'ana ma luna o kekahi mau kailaʻae, ho'ākāka' ia ma ka roundness, ka nui a me ka cementation i ke koena ai. hoʻomaka mākou me ke degere o ka polopelema. Ua loaʻa he pololei kaukaʻi ma ka paakiki, huna nui a me ka ano o ka amo i loko o ke kahua pōhaku. No ka laʻana, na (particles) lawe ma nalu kai koʻo, a me ka Hone kokoke i oleʻoi lua penei. Kamakawiwo Ole, a i mua o ka moe kolohe, i ka lepo pipili loa. Kēiaʻano o ka pohaku me ka nānā 'ana i ka lepo pipili haku mele' ana, ka mea i lilo i ka lepo, Opal, glandular, kalepona.

ʻano likeʻole o ka clastic pōhaku nui'ōpala

I clastic pōhaku i nānā 'ana i ka nui o ka'ōpala. Ke kaumaha ma muli o ko lākou nui breeds ua māheleʻia i loko o eha pūʻulu. Ka hui mua ka lanakila koena ai, nona ka nui, ua oi aku ma mua o 1 mm o. Ia mau pōhaku i kapaia nui-fragmental. Ka lua o ka pūʻulu nā koena ai, i ka nui o ka i mea ma ka laulā, mai 1 mm o ia 0,1 mm o. He one pōhaku. Ke kolu o ka pūʻulu nā hakina HEN i nui mai 0,1 i 0,01 mm o. Ua kapaʻia kēia pae silty pōhaku. Ka hope ha o ka pūʻulu Ho'ākāka 'argillaceous pōhaku,'ōpala hoʻi huna nui loli aʻe mai 0,01 a hiki i 0,001 mm o.

Mea Maluna o clastic pōhaku 'ole

Kekahi Mea Maluna o kaʻokoʻa i loko o ka 'ole o ka clastic, ahu iho, a kokua i ka hooholo i ka ano o ke kahua pōhaku. Pona hionapāʻili characterizes ka hou o 'ē aʻe papa o ka pōhaku. Ka mea, komo no ka lalo a me luna. Ke kaumaha ma muli o ka 'ano o ka layering hiki ke nānā' ia e ka 'ia i loko o i ka pohaku i hana. No ka paha, Hawaiian meaola hana hea mai ai diagonal layering, kai a me ka moana wai i hana i kekahi ole me ka laua kīhei pili, wai pele - kea-kīhei pili.

Nā kumu ma lalo i ka hanaia clastics, hiki ke hoʻoholo 'ano o kaʻilikai, a laila ma ke alo o ripple kaha, raindrops, mau māwae, a shrinkage, no ka laʻana, huapalapala o ke kai. Ke porous pohaku 'ole paipai i ka'ōpala hoʻi i hanaʻia e like me ka hopena o volcanogenic, terrigenous, biogenic a supergene ole. Papakaukau 'ole hiki ke nānā' ia e kekahi mau? Ueo o ke kumu.

Kind o ka pohaku haku mele 'ana

Clastic pōhaku e māheleʻia i loko o polymictic paha polymineral a monomictic paha monomineral. Ka mua, ma ka huli, me ka nānā 'ana i ka haku mele' ana o kekahi mau nā minelala hao, aka, ua kapaia lakou he hui ka mea. Lua o kekahi hoʻoholo i ka haku mele 'ana o ka mea pōhaku (pōaka feldspar a? Ueo). Ma polymictic? Ueo nā grauvaki (ka mea, ioiinyony (particles) o ka lehu) a me ka arkose ((particles) i hanaʻia ma ka make ana o ke māpala). Haku mele 'ana clastic pōhaku i ho'ākāka' kahua o ka hoʻonaʻauao o ko lākou mau ho okumu. E like me kēlā kahua, ho okumu i kona kaʻana like i loko o ka like ana waiwai. Clastic sedimentary pōhaku ka wā i hiki ke hai aku, i ka manawa, ma ka aoao he mea he neʻeʻana mea i loko o ka lewa, pehea ka mea, e haawi ma ka lalo o ka loko, a ola meaola, a ma ka kahua i komo i loko o ke kahua, a me nā kumu i loko o i i hana clastic pōhaku .
