Ris 3. Nizhnyaya chast' skopleniya dyun.

Polnyi vid fotografii privedennyh fragmentov nahoditsya nizhe po ssylke Obshii vid.

Vydelim sleduyushee: sudya po progalinam mezhdu dyunami (sm. fragmenty foto) i schitaya ih obrazovavshimisya posle smesheniya dyun v storonu mozhno schitat' chto pod dyunami kamnei net.

Marsianskie dyuny rassheplyayut, perevarivayut marsianskie kamni. Primerno kak Zemnye korovy travu. No sudya po primenyaemoi hitroi taktike dyun ispol'zovanie ohvatov, okuchivanie mozhno predpolozhit' chto kamni sposobny peremeshat'sya i znachitel'no bystree dyun, esli ne vse to mnogie. Izmenenie cveta poverhnosti i prakticheski polnoe otsutstvie kamnei v nizhnei chasti fotografii opyat' zhe govorit o tom zhe dyuny ispol'zuyut kamni v pishu i tak zhe kak i zemnye formy zhizni posle pererabotki pishi vydelyayut ekskrementy.

I eshe, nalichie kamnei do poslednih nizhnih dyun, svidetel'stvuet o nalichii organizovannogo delezha pishi mezhdu vsemi chlenami sem'i ili stada.

Fotografii dlinnyh dyun imeyut povtory, sdelannye rovno cherez odin marsianskii god. Smeshenie dyun sostavlyaet edva nablyudaemuyu velichinu v 1-2 metra, chto zametno tol'ko na fotografiyah samogo vysokogo razresheniya (smeshenie ravno diametru samogo melkogo kamnya).

 

Privedem eshe neskol'ko fotografii skoplenii dlinnyh dyun na kotoryh yavnye priznaki nekogo vzaimodeistviya mezhdu dvumya otdel'nymi skopleniyami.

No zdes' my hotim vydelit' kak zemnoe razlichie dyun mezhdu soboi po podobiyu razlichiya: oleni, losi, arhary tak i to chto uslovnyi obed dyunovogo skopleniya (sem'i, stada), po vsei vidimosti, ishodya iz nablyudaemogo razlichiya za dva goda, primerno raven po vremeni 500-1000 let. Chto daet razlichie v skorosti processov zhiznedeyatel'nosti k zemnym zhivotnym v usrednennom vide v million raz. To est' ih kosmonavt v sluchae nalichiya odevaet skafandr, a operator osushestvlyaet prinyatie resheniya ne sekundy kak u nas, a dni-nedeli dlya prinyatiya "mgnovennogo resheniya" ili mesyacy-gody dlya etogo samogo oblacheniya v skafandr.

Obobshaya mnogie fotografii dyunovyh skoplenii i fakt postoyannogo otsutstviya kamnei v progalinah mezhdu plotnymi i bol'shimi formirovaniyami dyun mozhno sdelat' vyvod. Dyuny potreblyayut kamni v pishu i rasstoyanie mezhdu skopleniyami dyun, dolzhno zaviset' ot skorosti rosta kamennyh zaroslei.

Chto iz obshih predstavlenii daet vremya v desyatki i sotni tysyach i dazhe neskol'ko millionov let dlya rosta kamnya do razmerov uslovnye: metry - desyatki metrov v diametre.

Opyat' zhe iz fakta ostatochnogo kolichestva kamnei v meste prohozhdeniya dyunovogo skopleniya, kamni mogut kak to vyzhivat' ili pryatat'sya vozmozhno pod poverhnost'yu ili imeya zashitnyi pancir' pozvolyayushii perezhdat' nashestvie. Opyat' zhe po vsei vidimosti dyuny imeya bolee temnyi cvet i otsyuda povyshennuyu temperaturu, razlagayut kamni kotorye v otlichie ot zemnoi rastitel'nosti soderzhat ne vodu a biologicheski svyazannuyu uglekislotu. Sobstvenno kamennaya dobavka v pishu, po-vidimomu, ne obyazatel'na, ili ne obyazatel'na dlya vseh vidov dyun. Nekotorye dyuny vpolne obhodyatsya kormom v vide uglekislogo gaza iz atmosfery i poverhnostnym sloem grunta. Eti razlichiya i opredelyayut skorost' peremesheniya, razmer, formu, cvet (himicheskii sostav) i dr. osobennosti.

No krome sobstvenno zhivyh dyun i ih skoplenii (sem'ya, stado, staya), opyat' zhe po vsei vidimosti na fotografiyah prisutstvuyut i rukotvornye dyuny (kolony mashin). Mashiny sozdannye dlya konkretnyh celei peremesheniya veshestva v zadannye raiony, po podobiyu teh zhe zemnyh mashin analogichnogo naznacheniya. Foto dyun mnogochislenny i NASA uzhe primerno 5 let issleduet opisannoe zdes'. Po lyuboi privedennoi ssylke vnizu stranicy imeyutsya dopolnitel'nye ssylki prosmotr kotoryh pozvolyaet vzglyanut' na evolyuciyu proishodyashego vo vremeni, po analogii i ryadom.
