Arrow-implication

Question

I'm writing my thesis and I need use a symbol of science implication that looks like

or maybe something like

but thicker.

I'm curious how to generate it.

This link How to look up a symbol or identify a math symbol or character? doesn't help me

Welcome to TeX.SX! Do you mean $\rightarrow$ , i.e. → or $\Rightarrow$ , i.e. ⇒ ? — , Jun 05 '16 at 09:31
@Saizou: See Comprehensive Symbol Guide please for an extensive collection of arrow commands. The tables therein from numbers 137 to 164 all deal with arrows — , Jun 05 '16 at 09:44
@Saizou The drawing is too imprecise to give a clue, sorry. Can you improve it? — egreg, Jun 05 '16 at 10:49
Aries rotated 90 degrees is close: https://upload.wikimedia.org/wikipedia/commons/thumb/0/05/Astro_signs.svg/2000px-Astro_signs.svg.png — Ethan Bolker, Jun 05 '16 at 11:14

First option (with STIX)

\documentclass{article}

\DeclareFontEncoding{LS2}{}{}
\DeclareFontSubstitution{LS2}{stix}{m}{n}
\DeclareSymbolFont{arrows3}{LS2}{stixtt}{m}{n}

\DeclareMathSymbol{\saizouimplies}{\mathrel}{arrows3}{'053}

\begin{document}

$A\saizouimplies B \rightarrow C$

\end{document}

Second option (with NewTX)

\documentclass{article}

\DeclareSymbolFont{symbolsC}{U}{ntxsyc}{m}{n}
\DeclareMathSymbol{\saizouimplies}{\mathrel}{symbolsC}{74}

\begin{document}

$A\saizouimplies B \rightarrow C$

\end{document}
